I have 28.5 week red sex-links(5), and a black sex-link roo. I also have 18 wk old EEs (2), Cochins (2), and BJGs(2). Out of all of these, only one girl is laying 5/7, and one is laying 3/7days. The other reds are not laying at all . Here is how I raise them. They free range on 1/2 acre (no place to hide eggs) and have PLENTY of calcium as I live on the gulf coast and get free Oyster shells and just boil and bash them. The eggs they lay are not soft at all, nice and thick shells, and also they get dinner scraps or treats at the end of the day. They ignore the coop and sleep in the trees, and only go in there to lay. They seem VERY happy. I live in lower AL and have wonderful soil full of bugs and worms, and perfect for dust baths. They could easily leave the yard but never do. In fact when they accidentally have gotten over the fence, they immediately panic and dart back over into the yard. I do have a dog, he chases them once or twice a day but just a little run through the flock, nothing crazy, they sit together fine most of the time. He mostly chases the younger ones before I give him a swift kick then he is over it. They LOVE me. They have plenty of fun places to dig and perch. So WHYYYYYYYYY are they being so stingy with the goods?
