So I just got back from a week away from the chickens... which means I spent a week worrying about their care. This morning, when I went out to check on them, they were RAVENOUS. They all leaped out of the coop and practically attacked me as I tried to feed them. Now some of the leghorns are gasping -- heads tilted back, mouths full of chick starter. And a couple of them are salivating heavily... kind of foaming at the mouth. I think they ate too fast, and the food built up at the top of their throats, because it doesn't even feel like it's getting to their crops. I massaged one of them in hopes of breaking up the chick starter and helping it go down. Should I give them water? Massage them more? HELP! What do I do?
