I have six hens and my only ameraucana lady has stopped laying and started brooding. She is one year old has plenty of yard to roam yet she has been staying in the coop keeping the other eggs warm. I haven't seen her cute green eggs in about 4 days. She typically lays every other day. I feed them a 20% protein lay mash with calcium. No rooster. Is she okay? Should I worry or take action?
