I have 2 older chickens (1year) and introduced 2 younger chickens (just starting laying now)about three monts ago, we did all the right things to integrate them and all was going well until.....we got a Grandpa feeder..... the older chickens won't let the younger ones feed and until we reintroduced the trough feeder the younger ones were making the most AWFUL stressed noises. Now the big ones are being even bigger bullies than they were before - chasing, pecking, not letting them feed from either of the two stations. (we also didn't get any eggs from the younger ones today We have kept the Grandpa feeder open - we want to exclusively use the Grandpa feeder so we can go away and have someone feed them daily - the sparrows are getting all the food. They are almost the same size now. They freerange our 1/4 acre section about half the time, but when we are away we want to keep them in their coop (5mx5m) Can anyone help please ! Will this sort itself out?
