I have a first-timer who is sitting on 3 eggs. I have been taking and eating her eggs until I notice she was starting to sit on the eggs. Im going to let her try and hatch these three but only if they are fertile. I have tried to see the "bulls-eye" on the yolk of the ones I eat but I have not seen it. She shares a space with two roosters but neither is particularly aggressive in the mating department, at least from what I have seen. Anyway, I am going to candle her eggs, and I want to do it sooner rather than later so she doesnt waste her time if they are not fertile. What day is the best day to see something by candling? I need some expertise advice on this for sure! Thanks to anyone who can offer a suggestion as to when and what to look for. Thanks again.
