I have buff hens that was setting but a dog got into her eggs and ate 4 and I now have 18 left she would not go back to her nest and I was glad because it was not in the hen house which if she was I would not be asking these Questions. The eggs where not cold but not real warm ether. Now how hot should the incubater be and how long well it take the eggs to hatch the full 21 days or less. And if they do hatch how long do they stay in the incubater and what do I feed them in the incubater and how long under a heat lamp. Boy it sure is easier when they raise there own.
