I just found our newest chick dead this morning, and am not completely sure why. Due to some unexpected roosters in our bunch, we have 3 different ages in our 4 chickens...two are 5 mos. (black sex linked, production red), 1 is 3 mos. (barred rock), and the newest one was 9 wks., and a leghorn. So the little one has wanted to get in with the big ones, and has tried a few times, but kept getting pecked and scared. So we've been keeping her in a cat carrier inside the coop so that everyone can see each other but not hurt her. Yesterday we opened her door, and she went out in the run with the others, but quickly got pecked and scared. She also got wet, because it was rainy and cold (she has all her feathers). I put her back in her carrier. Last night, I went out to close up the coop, and she was really talking, so I held her for a bit (I have developed a soft spot for her). She immediately settled right in next to me and started trilling, and then fell asleep. I did notice that she was kind of wet still. I had read on BYC somewhere that a good way to integrate new chickens was to let them roost together, so that's what I had in mind last night. I put her in her carrier, but with the door open, so that she could roost with the others if she wanted. Well, she did come out, and I found her in the corner under the perch this morning. I can't see any injuries on her, but she is definitely dead and already cold. Sooo, now we are really sad (my oldest DD is very, very upset), and not sure whether she got pecked to death or something else happened. I feel like I need to understand what happened, so that we can decide whether to try and introduce another chick or just keep our three. And is there something different we should do next time if we do try again? Also, any tips on burying this chick? I'm realizing I'm not prepared for this phase of animals (have never had a pet die, or anything!), but am needing to figure it out, particularly for the kiddos. Do people bury chickens? Dispose of them some other way? Help! I'm pretty new to BYC and this is my best guess for which forum to post this message in; please let me know if it should be elsewhere (e.g., chicken behavior?) Many thanks in advance.
