I have one hen that always has cracked eggs when they are collected from the nesting boxes. It seems like these eggs are being cracked as they are being laid, the crack is always a pressure crack right at the end of the egg. Should I be very concerned that this hen will eventually become egg bound as her eggs get bigger? I don't really know how to deal with an egg bound hen or how to tell if a hen is in that situation. My hens are by no means pets, so they are not handled with ease. Any advice is appreciated.
