Ok, so I have a very small flock of chickens. I originally had 3 hens and a rooster but we wanted to expand so we bought 4 chicks from a friend of mine (it turned out to be 3 pullets and 1 roo)... At 1 month old I began putting them outside and while I was away at school a dog dug under the fence and killed the 3 pullets and one of my hens. Now my baby roo is 4 months old and the lead hen still pecks at him if they are in the run together and as soon as she starts, so does my grown rooster. So we decided to expand the run and add a coop. (originally it was a 6' by 8' run with a hutch, plus they free range when I'm home) now the run will be 10' by 18' and the coop is 8' by 10'. We have the extra part already built and attatched, all we have to do it take down the wall of the old run and it will be finished. My question is, should I wait to take down the wall and let Rocky (the 4 month old) get used to it first so it will be more like his instead of thiers? Rocky is already almost as big as my other rooster so I'm pretty sure that he will grow to be the dominant rooster and the reason we are expanding is because my hens are only aggresive when they are in the run with him. Please help me out... I hope this question isn't to confusing, I wasn't really sure how to ask it. Ps- I know that the hen to rooster ratio is off but I have 2 hens in the brooder and we will be getting more in the spring... That's the best I can do for now.
