I'm new to the whole chicken thing. I got 25 chicks in March 2008 from the local farm supply store. Ended up with about 13 hens. I lost only 2. When they finally got big enough I built them an 8' x 12' coop and was going to let them free range. That lasted about 6 weeks and was getting about 4-6 eggs per day. Then in late august we had a coyote? attack in the middle of the day. We found 11 piles of feathers. The next week I got (2) - 18 week old delawares that each lay almost every day. My neighbor gave me (15) - 20 week old OE hens and none of them has ever laid. After the massacre my first chickens stopped laying and havent started back. They eat a layer ration and show no signs of disease. They are cooped at night and in a 15' x 40' run during the day. Someone told me the ratio of 23 hens to 4 roosters could be stressing them. Any other ideas.
