I agree. That is the case sometimes. I toss eggs that I think are too small for people eating or just crack them and let the birds have a little extra treat right there.It is possible for a chick to be too big to properly turn all the way based on the size of the egg. I have had this a few times. I always thought this is why it is not recommended to hatch pullet eggs if they are extra small, but to select for uniform overall size. I have had some small eggs pip in the middle due too big a chick. They usually can't be saved when that happens. I also have had chicks get mostly out only to take too long and get glued to the shell resulting in my having to peel them and bathe them before returning them to the Bator to dry.
That is the case also when crossing up the bantam hens with LF roosters. If you end up with chicks that are too large for the shell, they tend to perish before they can postition.
