my 8-day olds seem to be bored! They keep squabbling with each other and flapping around the brooder. I know its not a space issue..I think they are just bored. Every time I go over to say "hi" they keep running over to the front of the kennel like they want to get out. I'm thinking about taking them out for a little while this evening so they can play on the grass, but while I'm gone all day, any suggestions for something fun to play with that is safe? How about a cardboard toilet-paper roll thing?
