I have quite a problem with my 12 white leghorns. They are 9 months old and most are laying blood streaked eggs. Their vents are bloody, as a result, I've had to keep them apart. Two have died. I also have silkies in the flock and have never had a problem with them. I'm feeding 16% laying feed, plenty of water. They have nice clean living conditions and plenty of room. I can't understand why they are the only ones having the problems. I've googled and googled and cannot come up with any answers. Any imput would be greatly appreciated. We love our girls and hate this happening to them
