It's one of my insane EEs. He's one of the cockerals, and they're fast little boogers who don't let us near them. Last night I noticed one was sitting next to the water with ghis feathers all puffed up. I walked over and he didn't run away. It's been chilly and rainy here. They are about 6-7 weeks old, and it's been so warm the last month or so, I turned the heat lamp off about 2 weeks ago and they've been fine. He felt cold, though, so I took him back into the chicken shed (he was outside, I have food and water inside and out) and turned the heat lamp back on. Is there anything else I can do for him? No other symptoms. His crop felt completely empty, which I have never felt on a chicken before! He was drinking, though, and ate a little bit of chick crumbles while I was watching him. He and the other EE cockeral are my dominant chicks and very skittish, so this is very unusual behavior. Is there anything else I should do for him or just wait it out and see if he gets better or worse?
