I have 12 hens that are just over a year old and going through their first molt. I also have 13 pullets in with them who are 8 months old. Since the older ones began molting egg production has decreased drastically to only 3 or 4 eggs a day. I was getting 15-18 eggs a day before. I know when they molt egg production decreases but why have my younger chickens stopped laying also? The younger ones lay blue and olive eggs so I can tell they aren't laying. Is it just because of the shorter days? I swear one of the younger chickens has patchy spots that looks like she's going through a soft molt but aren't they too young to molt?
