Usually they have to sit over a week before they will take chicksYeah if she gets in an egg box with eggs from my leghorn or other production birds that have slightly thinner shells she busts them.
I think I may grab two chicks and give them to her and see if she takes them and if not I’ll break her. She is too big to sit in that box all day right now. If I can’t find chicks today I’m just breaking her cause we have a 112 heat index today and through the weekend. :-/
