Hey everyone! I've been around for awhile but don't post very much. One of my hens produced an egg with a bumpy top end. I feed them layer feed and oyster shells as well as home made mash. They free range all over our mountain, but go to their coop at night. We've been lucky as they have a lot of ground cover and tend to hang with me during the day around the house. They are happy chickens! They have been laying for a few months but I was confused regarding this egg. Any comments?
