I'm new to the wonderful world of chickens, and just want to know what is normal. I have 4 hens, 2 Ameraucanas and 2 Silver Laced Wyns that are about 7 months old. About 2 weeks ago my Ameraucana (Dumpling) stopped laying eggs. The others have slowed down to 3 a week, but have not stopped laying. There is no sign of molting or physical problems with her. However she doesn't seem as perky as the other hens. I'm not noticing others being mean to her, but she doesn't sleep on the perch with the others anymore and is always in the outskirts when the chickens are in the yard. Is she being ignored because she isn't laying? Is she depressed? Is there something I should be concerned about?
