Well I have 12 chickens (all hens.) one is young so she doesn't lay, bit the other Ellen lay eggs everyday. Now, I know that during the cold time of the year, (I live in nh) that the hens will stop laying unless certain measure are taken to keep them going. I have personally wrapped up they're run so no cold or drafts can get in, I set up a timed lamp that runs 14 hours a day, heated waterers and I have some oyster shell in a seperate dish for nice strong eggs. But lately, instead of getting 11 eggs a day, I only get 7 or 8 if I'm lucky. Every now and then I'll even get a shellless egg that they eventually attack to eat. I just want to know if there's a way to get my 11 eggs a day back! If it helps I have brown leghorns, white leghorns, Rhode Island reds, and a polish mix.
