Cheeto is a 1 1/2 year old bantam mutt rooster. I've been away from my chickens for a little under a week, and when I came back yesterday night, he and the rest of the flock had bulging crops. I'm assuming they haven't been getting enough food for a day or two and filled up their crops yesterday morning. All of them except him and his sister are fine today. His sister has a bit of an impacted crop, but is acting completely normal, and I can easily treat it. Cheeto, however, is walking with his neck hunched in, stumbling, and occasionally falling and sitting on the ground for a bit. I've put him in a separate pen from his flock (three bantam cockerels, a bantam pullet, and three bantam hens) with his sister to keep him company. He got so excited to see his sister that he tried to wing shuffle, but ended up running into the wall a couple of times. I asked the person who was feeding them what kinds of scraps she gave them, and she said some fresh leftover spaghetti salad. Another thing I noticed is that they all have a weird smell on them (not their breath) and assumed it was because of the scraps they've been fed. I also saw some watery green poo. This is Cheeto. I'll upload a video as soon as I figure out how to put it on YouTube. His comb is drooping a bit and has some dried blood on it since one of my other roosters got out and beat him up a couple weeks ago. Here's him laying on the ground after stumbling sideways several times.
