Thank you. The roo is a great guy. We had to get rid of a different roo bdcause he needed more hens. If he tries to breed them and they don't submit he backs down. I even had 2 infertile eggs when I incubated.They might be stressed. 1 rooster should have more than 3 hens. I have four hens and 1 rooster, and one of my hens has stopped laying too. I'm almost 100% she is just stressed because of his "needs". But it depends on the rooster. So watch him. If he has to chase them to mount them, they are probably being mounted too often, and would like some more 'sisters' to share the load.
