I have three Brahma hens. As soon as the grass started growing this year, they started grazing, which is normal. But one of them doesn't seem to be breaking down the fibers. They all get the same food with oyster shell and grit added in. They spend most of their day free ranging the yard. And they all seem perfectly healthy and are all laying eggs as usual. So is fibrous poop common in chickens? I have studied the poop chart and it doesn't have this one. The only way I know it's fibrous is that it has been warm here and the poops dry quicker and fall apart when I clean them up.
