I have four light sussex hens and they are gorgeous. However, one of them is not laying right. I often find rubbery eggs with no shell and today I found a yolk in a rubbery sac and an egg white in a rubbery sac. The yolk sac was considerably bigger than the one with egg white alone and they were found next to each other on a gravel path. I have no idea what is wrong and wondered if anyone has any experience of this please. All the hens are well though one has a wet mucky bottom.
