How much light do they get a day?I feed them layer pellets. I will feed them some vegetables and fruits that are about to go bad, my kids are really picky about what fruits they eat. We also give them the heels of bread and leftover pasta noodles when they are available.
My chickens are all just a bit over a year old. This is the first time I have experienced broody hens. Two of my orpingtons went broody for a few days, but it is my splash marans that has continued to be broody for a couple weeks now. I feel sorry for her and thought about getting some hatching eggs.
During the winter I was getting a similar yield. It has been cold and windy here (in the SF bay area). The weather has multiple personality disorder! For a few days it was hot like in the 90s then it dropped to the 60s, it has been raining sporadically, and the winds have been really strong and cold. Maybe it is the weather?
