I am attempting to hatch some silkie eggs for the first time, and I'm all around fairly new to chickens. I ordered 21 eggs, gave 7 to my broody hen and put 14 in the incubator. My first question is for the chicks under my hen, I will need to put a heater in her nest when they hatch right? I know most people say to not give your chickens heat lamps in the coop in the winter, but does that change when you have a hen with new chicks? If so, what temp does it need to be? My second question is, how many chicks can a silkie typically care for? My hen only had room to sit on 7 eggs, but once hatched can I give her some of the chicks that are in my incubator? I have read they usually have a better chance of survival when with a mama so I'd like to let her care for as many as she can.
