15 to 20 eggs under two hens? I'd say that is way too many. Discard the obvious duds. Ideally you hens should have a clutch of 5-7 eggs each. Any more and you run the risk of having a very poor hatch and the chicks that do hatch are more prone to problems. Better to have fewer chicks that are 100% (or nearly) healthy and strong. Also, don't forget that the moms will have to care for all those chicks once they are hatched!

I take it your broodies are seperated from the rest of the flock, both for safety reasons and to avoid the problem of the laying hens adding eggs to the broody's clutch? If not, you need to mark the hatching eggs with an X so you can tell them from fresh eggs...

Good luck with your chicks! :)

After actually counting them I realized there are only 11...but the hens are silkie bantams...is that still too many? Yes they are separated.
