So far one of my broodies has four babies, and I think I can hear a fifth tapping away inside. A sixth I picked up briefly and felt something shift, so there's a chick in there, but no tapping. So don't know if the hen will hold out long enough for that one. (If not, I'll try sticking it under the other hen whose babies started a day later.) The other broody has a Silkie and a Belgian D'Uccle so far and two more pipping the last I checked. The fifth egg under her was silent, so we'll see. They are both being good mamas and the chicks haven't had any problems so far.
