I have a cuckoo marans hen that is 6 months old. She went egg bound for her first egg. She passed the egg. The 2nd egg was beautiful. The third was a soft crushed up looking egg. I got her as a chick from a somewhat local private breeder. I'm wondering how much genetics could play into this problem and if she comes thru this problem (again) and successfullly breeds/lays. Would her offspring have this issue? She hasn't been with a rooster as of yet. Would it be most advisable to exclude her from my breeding program? And if I exclude her, should I also exclude a rooster that came from the same source? I have another unrelated rooster, so its not going to pose a problem to exclude those two. She was my only cuckoo marans hen so I would have to find another source to replace her.
