I had a BO hen go broody (for the 1st time) just after I put 6 eggs in the incubator (also for the 1st time). I just snuck 2 chicks under her last night, and it's going well except that she is still sitting! She is fine with the new chicks, but wants more, so I'm putting the other 3 that hatched under her tonight. If that's not enough, I don't know what I'll do! I also asked for advice first, and I know some people have had their chicks killed by a broody. I took the chance and it's working out. Maybe it would be less risky for you to just get a few hatching eggs and let her hatch them? Good luck and let us know what you decide!
