My Americana chickies are 8 days old now and I still have paper towel covering their shavings because some of them were trying to eat it. They make the paper towel such a mess, that even with just 27 of them, I'm changing it twice a day. Can anyone tell me how soon they'll stop eating the shavings so they can just be on that without the paper towel? Oh, and is it OK to give them a little finely mashed hard boiled egg now as a treat? My daughter gave a few of them a little yesterday and they LOVED it, but I just wanted to make sure its OK for them to have at this age. (I think I'm spoiling them all ready!)
