My Buff Orpington went broody 4 weeks ago in Virginia. This being my first broody hen I made sure she was in a cozy coop with lots of wood shavings by herself (Eglu Omlet).One week in I put 9 fertile eggs under her and now they have started hatching. Day 18 after sitting on them she hatched her first chick; day 19 her second and third and the weather was fine, 70 to 85 degrees. Now the weather has turned cold, 48 degrees and 26 mph gusts = 44 degrees. Should I supplement heat the little coop? Should I do anything other than what she is doing? I did put a small waterer and feeder in the coop so she doesn't have to come out into the blustery cold wind.
