I have an 8 month old Delaware that is huge. She is 22" tall. She has been laying huge eggs, some double yolkers, a few a week and now she is crowing??? I only have 7 hens various breeds that are also laying so I don't have too many to not have a roo. She just started sporadically crowing this last week. Also she does not have spurs. What is with her?? anyone have any suggestions?
