I have an Americana Cross Hen that was broody for 4 weeks and I finally put 12 fertilized eggs under her (also blue Americauna from a farm with a rooster). The eggs started Hatching yesterday (day 21) by this morning we had 9 hatched. 3 eggs haven's shown promising signs so we are giving them 24 more hours and then removing them. It is cold here (-5 C) the brooder pen (which is inside a insulated but not warm coop) has Hay bales around all four sides and a heat lamp above it. The water has not frozen in it for the last 2 nights. MY question is should I help the chicks find water and food? The chick food and water are within 18 inches of the hens nest, but she is still sitting on her chicks and they are not coming out from underneath her. When should I intervene? I want this Hatch to be natural as possible but I am also concerned then hen my sit on them while they starve to death. Any Advice??
