One of my silkies has been broody for awhile and hatched out some eggs yesterday apparently. I went out this morning to feed them and give them scratch and found one dead behind the coop and one dead under it. I opened the roof to the house up and there is one baby that is still alive that she is sitting on. It has been getting cold here at night (upper 20's to low 30's). I don't know if I should take the baby away from her and raise it in the house or let her keep it or move her to another area where her and the baby can't get outside and away from other chickens. I would hate to have to raise it myself because being it is the only one, it would be harder to introduce it to the flock again. What should I do?
