So I moved the girls out to the coop this morning. So far so good. They’re still trying to figure out how to get up to the roosts. Even with a stool and some logs for them climb up to it on. BUT, I put some regular horse stall PDZ in the poop board and a bit got on the floor and they’re digging around pecking it and possibly eating it? I’ve read on here and other places it’s ok for older chickens to eat but they are about 6 weeks old. Is it ok for chickens this young as well?
