Is it normal for BLRW's to lay huge eggs ? Hers are all huge and they won't fit in the egg cartons, and none of my other Wyandottes lay eggs nearly THAT big. She's been laying for 4 months now, and the shell is really thin. I just don't want one to break while she is laying it, and hurt her. I always have oyster shell available, and give milk as a treat to help the egg shells. Should I be worried at all ?
