Per 
Special Containment Procedures: All known instances of SCP-XXXX are to be contained in the exterior confines of Provisional Site 37-C, located in ███████, Colorado. Site 37-C is to be fitted to house Doctor ███████ indefinitely. In order to maintain the appearance of Site 37-C as a residential home, instances of SCP-XXXX should be transferred to Site 37 for research and testing. The population of SCP-XXXX instances is to be maintained at the discretion of Doctor ███████.
Instances of SCP-XXXX-1 are to remain in Foundation custody under low level security. In the event that the stock of SCP-XXXX-1 becomes excessive, instances are to be manually destroyed by a single member of staff, and disposed of using traditional means. SCP-XXXX-1 is the only part of SCP-XXXX to exhibit anomalous behavior, as such, any matter originating from SCP-XXXX (including feces, feathers, and body parts) can be disposed of according to Foundation guidelines for biological waste.
SCP-XXXX-2 instances are to be removed using structural and cosmetic surgeries in foundation custody. Civilians who are affected by SCP-XXXX-2 are to be interviewed regarding the nature of SCP-XXXX-2 and subsequently amnesticized. As of 2020-06-27, all future testing of SCP-XXXX should be approved by the joint discretion of Doctor ███████ and the acting site director of Site 37. Additionally, under no circumstance should individuals be exposed to the effects of SCP-XXXX-1 multiple times (see Addendum SCP-XXXX-D for further information).
Description: SCP-XXXX is a species of animal that superficially resembles domesticated chicken. Behavior of SCP-XXXX instances is believed to be non-anomalous. SCP-XXXX-1 is the designation given to the furcula1 of an SCP-XXXX instance. In the event that two individuals pull SCP-XXXX-1 from either end and break it2, an instance of SCP-XXXX-2 will spontaneously form between both participants.
SCP-XXXX-2 instances are a connected bridge of tongue tissue spanning between the two individuals responsible for the destruction of an SCP-XXXX-1 instance. These functionally appear to be a single, extraordinarily large tongue. Typical instances of SCP-XXXX-2 measure 40cm long from lip to lip when taut. SCP-XXXX-2 instance produce sensation for both individuals and reactions to various stimuli have proven to be consistent with non-anomalous tongues. No recorded instance of SCP-XXXX-2 has been shown to significantly change the taste preference of affected individuals.
Foundation medical procedures have proven effective at removing SCP-XXXX-2 with no long term side effects. This treatment is recommended for all personnel and civilians affected by SCP-XXXX-2, except in the case of long term study.
Addendum SCP-XXXX-A (Discovery):
SCP-XXXX was initially discovered by Foundation agents embedded in local law enforcement in █████ County, Colorado. David ███████ and his daughter were found afflicted with SCP-XXXX-2 and SCP-XXXX-1 was quickly determined as the cause. Following surgery and recovery, an interview was conducted with David ███████ in order to determine more about the origins of SCP-XXXX.
<Begin Log>
Agent Melissa ████: Good evening Mr. ███████, I hope your recovery has been going fine.
David ███████: I, uh, yeah, thanks.
Agent Melissa ████: Today I'd just like to conduct a general interview about SCP-XXXX.
David ███████: That what you lab coats call my tongue?
Agent Melissa ████: Yes Mr. ███████, that is the designation for the general anomaly that has affected you and your daughter.
David ███████: What's to know? We snapped the wishbone and suddenly my mouth is forced open and everyone at the table starts screaming.
Agent Melissa ████: Yes, we are familiar with this series of events on the 14th.
David ███████: Then what do you want to know?
Agent Melissa ████: I would like to ask you where you bought that chicken.
David ███████: Didn't.
Agent Melissa ████: I'm sorry?
David ███████: Didn't buy it, I mean. Raised it.
Agent Melissa ████: From an egg?
David ███████: Er. Now that you say that I guess I did buy her when she was young. Damn I forgot about that, me and Lena were at the fair, you know, where the farmers and kids were showing off animals? Anyway some hippies or whatever the fuck were running around protesting farmers and all that. I could tell it was upsetting Lena, she did 4-H a couple years back and raised some animals and these fuckers didn't know what they were talking about so I was actually about to leave when I saw where they were grouping around. There were these farmers or breeders, I dunno, trying to sell some younger animals, you know, young hens bred from the animals they were just displaying. Anyway I was pissed at this point and thought fuck it, if these idiots are gonna piss me of, I'm gonna piss them off right back. Lena always wanted a chicken, that's why we signed her up for 4-H after all, but she still hadn't grown out of it, so this seemed like the perfect opportunity to get one and see if I can't teach her some responsibility.
Agent Melissa ████: So you bought a hen?
David ███████: Damn right I did, got a male too, should've seen the look that PETA goon gave me, looked like she was trying to kill me by thinking about it hard enough or something haha. Brought it home and helped Lena set up a coop in the backyard.
Agent Melissa ████: How long ago was this?
David ███████: Uh, shit I dunno, couple years. Actually no, it was just over 2 years ago, because that was the year that Lena wearing makeup everywhere because she was a high school freshman and all the girls would hate her if she didn't or whatever. Yeah and she just did her ACTs so that's gotta be it.
Agent Melissa ████: I see. And was there anything in particular about how they were raised that stood out?
David ███████: Not that I can really think of. We raised them for a while, Lena gave them names, we started getting chicks, raised them too, had eggs for breakfast, normal chicken stuff.
Agent Melissa ████: Where did you go to have them slaughtered?
David ███████: Did it at home, I looked it up on YouTube and wanted to show Lena how to do it, in case she was ever stranded on an island or something, you know. She didn't seem too into it and to be honest she hadn't been into chickens for a while, but we did it together, and she helped her mom cook it.
Agent Melissa ████: I see. Well, thank you for your time Mr. ███████, I'll let you get back to resting for now.
David ███████: When can I see Lena?
Agent Melissa ████: If her operation goes well later today, we'll see if we can't move you both into the same ward.
David ███████: Thanks, Melissa, was it?
Agent Melissa ████: No problem at all Mr. ███████, have a good afternoon.
