i'm new to the chicken thing, picked up a roo that is just about 6 mos old.. had him for about 3 weeks now..he seems normal, but today after i cleaned the coop out and raked the dirt underneath, he layed in it and dug a hole. then he scratched around with his beak and made it look like a little mud nest...why did he do this? is something wrong? or is this normal roo stuff? my pullets dont do this, but they are much younger... here's some pics... here's Big Red..
