My husband just built me a bigger brooder for our girls and put lino on the bottom for easy cleaning. They have been moved and seem to be loving the extra room however seem to be sliding all over the place. I have read where people put lino in the coop so we didn't think much about how slippery it would be. I don't want to see them hurt, Is this something that I need to be concerned about or will they get used to it?
