I have about six broody hens right now in boxes in the coop along with unused boxes full of eggs for the laying hens. Still, the hens that want to lay a new egg come in, ignore the unoccupied boxes and find the ones with broody hens in them. Then the layers kick her off her clutch, lay their egg, leave, and the broody gets back in. The problem is I don't always catch this though I know it's happening, and more and more eggs are added to this broody hen's nest. This means eggs are being incubated at different times and the nest is filling up so much that some eggs are exposed to the open and moved around the box so eventually each egg has been cooled down (embryo killed). How do I get these laying hens to leave the broody hens alone and lay in one of the provided boxes? I cannot seperate chickens or put them in a different place, they must ALL remain in the coop. Also, I notice that some broody hens nests after about the second week just get totally messed up. The eggs get buried in the hay, the hay gets sticky and dirty, the eggs stick to the dirt and are all over the box and most of the time no chicks hatch. How do I prevent all of this?
