I originally had 8 hens from last year (2011) and i added in 10 more several months ago. They're mostly tollerating each other but we still have some occasional skirmishes and the older hens rarely let the youngers out into the run. They've been together all summer so we thought they'd have gotten their issues worked out by now but it's still going on. Everyone is getting enough to eat and drink since i have seperate areas set up for them. But we would like the younger girls to be able to putter in the run for more than a minute or two before getting run off and having to hide out in the coop again. THere's plenty of room for everyone just the older girls don't want to share it. Moving one group of them to a different coop is not an option for us. Any suggestions?
