I had to laugh because I've done that a couple of times when I have early layers. I grab the eggs and stuff them under my BlackJack, a black CochinX, I can get them out from her later on & they don't freeze. She has been broody all winter. Which brings me to my next question: should I give her eggs or chicks, if the weather gets above zero sometime soon? The coop annex isn't insulated. I can't break her of her broodiness, I tried last time & she sat for almost 40 days in Oct & Nov. took a couple of weeks to get back to normal & back on a nest by first week of Jan. Any ideas for my preety girl?
