We have 26 Black Star hens and 2 Jersey Giant hens. They are about 4 1/2 months old and are starting to lay. We have had a LOT of double yolk eggs so far but last night we got 2 eggs that had a skin instead of a shell. Is this normal?? And can a chicken lay more than one egg. Yesterda we had one lay on a nest all day. 9am,...one egg, 11am,...2 eggs,...1pm 3 eggs!! SAME chicken!! My last question. How big are the bantam eggs?!?! I think we may be missing them. Thanks so much!
