My hens are kept in a coop with no supplemental heat or light in the winter and I was wondering if upping their protein intake might spur some more egg laying? Right now I have four 3 year old hens giving me (if I'm lucky) about 2 eggs a week. They have plenty of food and water and while I understand that lack of light and heat will cause a drop in egg production, I didn't fathom it being this low. Neither light nor heat are an option for this coop; it's on the opposite end of my property and I'm not running extension cords that far which is why I wanted to ask this question. Thanks for any advice you have!
