I have 7 chicks in my coop now with a mama hen. I noticed they have started to peck at the bedding(it is straw, but its is in tiny enough pieces for them to eat). Its looks like they are trying to eat it. They are 2 days old. Should I get some paper towels to put over the hay? Also , they are in a chicken tractor that has a ladder..........I dont think the chicks will be able to get up and down it a night. Should I make them a box inside the coop or what? Thanks so much!
