In a nutshell: I have 5 chicks, 5/6 weeks old. The two youngest (and smallest) are at the low end of the totem pole but doing fine. My white leghorn had a massive bald spot and scab above her tail from pecking when we got her at 3 weeks old (my daughter insisted on THAT chicken, and she paid for her herself). But the scab completely healed and all her feathers are growing back in and she was doing really well. But I went out to run errands today (and actually buy a bigger brooder) and came home and she has had all her tail feather pulled out and was bleeding from the stumps a lot. I moved the other four chicks to the bigger brooder, washed off as much blood as I could and put her back in the smaller brooder by herself. But she's going crazy. She's squawking so loud it hurts my ears, and she keeps flying up/throwing herself against the chicken wire lid. We put her next to the other brooder so the chicks can hear each other but she's still just as frantic. What should I do? Should I spray her with blue kote and put her in the bigger brooder with them all? Should I put the other little one in with her? Should I leave her in isolation till she heals and let her be frantic? I'm building the coop next week and want to move them all out at the end of April but will that cause problems if they're separated until then?
