I tried to search this, but every thread that came up was about slow crop, or chicks with huge crops. My chicks have flat, empty crops. In the week that I've had them, they seem to be happy and growing. I see evidence of them eating, drinking and pooping, and they do not have any poop stuck to their vents. But I think it's very odd that every time I examine them, they seem to have no crop whatsoever. At first I figured it was just a coincidence that I happened to be checking them after their crops emptied. But it's been a week now, and I have not been able to catch any one of them ever with a full crop. If they were a budgie or a finch with this condition, they would be dead by now. I can't help thinking there must be something very different about chickens than about my other birds. I haven't been too worried, because they look and act fine. But now I'm beginning to wonder. Do I need to be worried? Could it be possible they are only playing with their food and not actually eating it? Could they actually go a week without eating and still look healthy? I really hope there is a logical explanation for their flat crops. But it does not fit in with everything I've learned from five years of raising baby budgies and finches. By the way, there are five of them, Lavender Ameraucanas hatched on 11-9-14.
