I am new to owning chickens and need some information on how to care for them. I currently have 5 chickens (3 roosters, 2 hens) of all different breeds. One of my hens started laying eggs within the past 3 weeks, she has been laying 1 egg a day, 7 days a week with a few days off at the end of every week. About 4 days ago she stopped laying completely and has been spending most of her time in the coop. She is usually very sociable and energetic. She does not appear to be sick. I am unsure of what kind of breed she is but have narrowed it down to possibly a Buff Cochin hen. Is this normal for her breed? Could it be the fall weather that has changed her laying schedule? Is there anything that I can do to increase egg production again? Any answers would be appreciated, Thank You.
