Hey Karen you could give her 4 bantam or 3 LF. Even if all hatch she could keep them warm in the cold. Just dont let them have acsess the snow (fast killer). The begining os October is not cold. The beginning of January is cold. Lost a little one during this time but have also had broody's raise several in 15/20 degree night time temps and 30/40 day time temps. My little a-frame is perfct for winter hatcherey but can be a killer during the sring, summer and fall temps The problem with Silkies is that they are very persistinat. I have had one sitt in the nest box for 2-1/2 month hatch some chicks and was broody 5 weeks latter. She is now raiseing some Silkie chicks.Silkie chicks for sale!!!
