Well, our hens decided they would sit on seven eggs and they hatched a few days ago. I feel bad because it is so cold outside. The two other groups of chicks were born during the spring and summer. Not the beginning of winter. One has died of unknown causes and the others are constantly huddled for warmth. Should we take them inside and keep them under heat until they are big enough? Our chickens are free ranging and this is not the adults first winter but the newest chicks are so young!
