Hi, looking for some help on understanding why our chickens' poop looks like this after being on roost all night. They have normal appearing poop during the day while free ranging. I have 7 adult chickens and four 21 week old chickens. I use PDZand diatomaceous earth in the pans underneath the roosts. 3 of the young chickens still aren't roosting at night. They would rather sit in the pan. I try to put them on the roost in the dark, but don't think they are staying up there. I say all of that because someone mentioned to me that it looks like chickens scratching through the poop to make it look like this. I just want to make sure there isn't anything wrong. I am hoping someone has seen this before. The white seen in the pictures is PDZ. I will also add that this is fairly new over the past month. Thank you to anyone that can help.
