Yeouch!! Now that's cold!
That's a win in my book. I love incubating
Are you sure she is done laying? Often hens will brood sporadically at first because they are not quite done with egg laying. I have a silkie right now that has been acting like a broody, clucking and fluffed up, off and on the nest, but she is still laying eggs. Going by what she has done in the past she will soon start brooding full time.
Do you have a guess at how far along they are?
