I am getting ready to set another batch of eggs from my girls. The ones I have questions on are FBCM and an EE. The FBCM eggs are very dark and thick shelled, I cannot see anything when I candle them. I can tell which end should be up in the turner, by the shape of them. For those that have sat FBCM before, I have read that they take an extra day or two to hatch, is this correct? If so should I give them a day head start? My EE lays a very large egg (sometimes jumbo++ depends on her diet) the shell is olive (most of the time) and I cannot see anything when candled. I also cannot tell from the shape (both ends look alike very uniform) which end the air pocket is in. My thought is to set them in a pan of luck warm water 1 at a time, (float test) long enuf to mark the air pocket, get them out and pat them dry (not rub). I dont want them in the water any longer than it takes to find the air sack and mark it on the egg (pencil). Anyone see a problem with this?
