So when you candle the eggs and see the airsac does that mean it's fertile? If it does not have an airsac is it not firtile or does every egg just get an airsac Or do the aisac have nothing to do with fertility. Extra question So can someone give baby chicks to a hen? For her to raise I have this one hen she is a very good behaved chicken and was sitting on her eggs a tiny bit but not to much. I took her eggs and I am incubating them so can I give them to her back once they hatch?
