Lately I've been getting large wrinkly eggs. Now I know about IB but have seen none of that. However there is molting going on and of course the weather and daylight is changeing. I think it may be comming from the back part of my coop hens where the lighting is darker. My coop is divided, the front has a window and the back has none. There have been some added pullets also. I've begun giving them a bit more scratch than usual and they've had a few more tomatoes than usual as the harvest is here. I've run out of AVC too which i've been putting in the water. I had this problem with one hen who was older for a time but she stopped and all eggs resumed normal shape. I've not gotten any unusually large, double yolked egg in a very long time. I can't remember getting any for some time. Lately however there are to many oversized wrinkly eggs. In my dels as far as I can tell. Most of my hens would be approaching two or three. There have been some young pullets added to the flock and some different breeds but they've been there for awhile. Though the pullets are starting to lay. My concern is I have egg sales and these eggs are unsaleable. My other concern is I need the older hens to replenish my stock come january hatching. Any ideas or comments.
