My 7 month old buff orpington hen went broody on me last week. I thought if I kept on kicking her out for a week or so she would give up...Wrong! Anyway, my roosters are only 3 months old so my hens eggs are not fertile. I got some eggs from a friend and slipped them under her yesterday. I have no experience with this so any advice would be great. I am very worried that if the babies hatch they will be soooo cold!
