I bought some hens today that were collectively sitting on about 27 eggs. The owner had no idea on how long they were sitting on them, but was going to throw them away so I took them and burned myself in my car on the way home to try to keep them as warm as possible. When I got home the hens would have nothing to do with them...should I try to incubate them? and if so, how would I even know when to stop turning and increase humidity? Thanks so much!
