Lately I've noticed several of my eggs are quite bloody. Should I be concerned? They have been laying about 5 months now and figured that their bodies should be used to the laying by now. I also noticed that my hens are being mated bare. I have 2 roosters for 20 hens and figured that should be a good ratio. I don't want to get rid of either because I like having a spare in case something happens to 1 rooster.
