Hi am a new member and this is my first post. I bought 2 rhode island red hens at a feed store a few months ago. I also have 3 other hens of a different breed. Just the other day one of the hens started making a rooster crow at 5:00 in the morning. I heard of butch hens before. Is this possible? This hen who thinks she is a rooster is twice the size as the others and her colors are so beautiful with greenish tail feathers. She even looks different from the other hens.
