I have six red sex links that are 22 weeks old. The first one started laying at about 19 weeks and now all of them are laying. For the most part all of their eggs are really nice and about the size of a large store bought egg. The chick that started first lays just about every day. About a week ago she had a problem where she seemed egg bound but with a little encouragment she laid a rubber shelled egg and everything seemed fine. For the last several days she has laid eggs that are twice the size of her nermal eggs. They are beyound jumbo and do not even fit in the jumbo egg carton. We ate them this morning and all were double yolks. This may all sound great but we are concerned that her eggs are too big and that it is causing a strain on her. She does seem fine and I watched her this morning when she went in to the nest box and laid her egg without much fanfare. Can there be a problem with my chicken laying very large eggs??
