I hope this is the thread where I need to ask the questions I cannot answer. I have a hen, 18 mo. old, who has always laid jumbo eggs and since she started laying has only missed 3 days to leave me an egg. I have her in a flock of 16. About a week ago I noticed her eggs where looking thin shelled and the small end looks wrinkled...almost like it "turned" when she was laying it. After their looking like this for 5 days I decided to break some for baking. The yolks have become more of an orange color...kinda like the yolk of a Maran egg (This hen is a mutt). The yolks are very soft to the point that even dropping them in the bowl burst the yolk. All the other hens eggs are fine...good hard shells. I feed my hens laying pellets, fresh veggies and snacks of bread. I always have oyster shell in the hen house for them. This really is a puzzle. Anyone have any idea what is going on?? Thanks!
