Hello! I have a flock of 17. I Roo 10 hens and 6 pullets. My pullets are ISA browns. I have never had them before and are supposed to be comparable to leghorns as far as productivity. They started laying right after Christmas and over the past 10 days I have consistently been finding a soft shell egg (frozen like a rock!) on the poop trays under their roost. They have been great layers. I faithfully get 5 eggs from them daily. I know double yolkers are common in pullets as their hormones are balancing out but can that alao be the reason for multiple soft shells? I mean these girls are laying machines and only 19 weeks. Do I need to change anything diet wise? They are on a high protein and calcium diet. I do a 2:1 ratio of meat bird feed and layer feed. I also have pyster shells out for who ever needs extra. I am hoping they grow out of it before summer when they eggs wont be freezing so no one decides to eat them. Last thing I want is an egg eater!
