My 6 new pullets just began to lay about a month ago. They are a production brown egg layer. All but one chicken are laying good strong eggs. One chicken seems to be laying soft shelled eggs at odd hours of the night or morning and it appears that the chickens have eaten the egg by the time I find it just a soft shell. They are about 23-24 weeks old and I am just finishing up the grower pellets I gave them. I will be staring laying mash either this week or next. I am giving them probiotics in their water and all appear to be healthy. I am wondering why this one chicken is laying soft shelled eggs. She seemed to be laying hard shell eggs at first, but now seems to always lay soft shelled. eggs. I have supplemented them with free choice oyster shell. I am not sure if it is the fact that they are not on layer mash yet or if it is just a defect in the one chicken. Anyone have any ideas
