I've raised chickens for 6 years but this is my first year with a rooster. Since I have one girl who goes broody, I decided to let her hatch some eggs this spring. She's been very contentedly sitting on 6 eggs for 15 days in a big plastic covered kitty litter box in a separate chicken house. My question is, when the chicks hatch should I give her a different kind of next? I can't imagine newly hatched chicks being able to get out and back in the nest box.
