I have two eight-month-old cochins and they're not laying. I feed them laying pellets and they also eat chick grower cumble because I also have four four-month-old silkies in the coop with them. They get occasional treats of bread, watermelon, lettuce -- just about any vegetable scraps (except garlic, potatoes and onions). I've also been blocking off the nesting box at night because they've been sleeping in it and pooping all over the place. Does anyone have suggestions what I can do to help these hens produce???? I'm frusterated!!!!!
