My little hen hatch 12 chicks 4 days ago, Their all fine, i just make sure their in the nesting box with her at night. during the day she will sat on the ground and they will be under her if not walking around the pen.
I also have pipping today! My White Rock only has three BA/EE eggs under her, and two of them are pipping, and the third I can hear a tap, tap, tap! WOOHOO! Mr. Roo did his job, and Momma Hen did hers!!! Now if I can only stay away and let them do their thing. I can't wait to see those fuzzy butts!
Oh, btw, can you hear any chirping yet? I can hear one of mine chirping.
The only problem I've had with hatching under a broody hen is when the hen has a lot of eggs she is hatching, sometimes a shell might get capped over the air cell of an unhatched egg, killing the other chick. So, depending on the situation, I will sometimes watch and steal the egg shells as they hatch.
That said, I had 8 hatch last week with no troubles at all and no intervention from me.
