Hi all. I have some 8 day old guinea chicks that have to be moved to the barn today. 18 guinea chicks in the living room is getting too noisey! I think they will stay warm in the barn, I just built a new brooder box. I will put the heat lamp in there with them. My question is what can I use for bedding? The bottom of the box is plywood...Also, can I throw some hay in there with them? Maybe some fresh picked grass or vegetable peels?
