We had a hen that has been setting on eggs for almost 3 weeks now. Well, mistake or not, we needed to move from where she was sitting. We put her in a dog house with a box in it. Filled the box with wood shavings and such placed her eggs and her in it late yesterday evening hoping she would stay there due to the dark and remain there afterwords. Well, we came home just a little bit ago and she is standing on top of the dog house - eggs are cold - maybe 45-50 degrees? They could have been uncovered for 8 or 9 hours (she was on them when we left this morning). Are they gone? Is there still a chance we could put them on a heating blanket of something and try to get them to hatch? She is making no effort to stay with them now and will probably break them if we force her into the box we made for her. Please advise ASAP! Thanks!
