I have a flock of 8 hens that are 15 months old living in a coop and enclosed run - although they are frequently out grazing in the yard. They are a well behaved flock, in that they tend to stay close in the back yard, go into their coop every night and are great layers. The coop is small for them, and there is some butt picking that occurred, especially when the weather is bad and they have to stay enclosed in that small space. My hubby has built a much larger coop/addition that will be finished soon. It is a separate "building" with roosting and feeding space. It will connect to the original coop, and the hens will continue to lay in their existing nest boxes. This will give them much more space, especially when bad weather comes. I also have 3 new birds, 2 hens and a roo that are 11 weeks old, still living in the brooder in the garage. They free range most of the day in the front yard. The roo has crowed but is still very docile to me. I was thinking that once the new coop/addition was completed (2 weeks?) I'd move the new birds to that space and keep them closed in for a few days so that they'd know this was their new home. Then open that space up to the older birds and make sure I am home so that they could all free range outside with the most space. The other option I thought of was to open the new coop/addition and give the older birds more space and wait for the new birds to be 16 weeks and on the layer feed and place them in the new coop at night. I wondered if the new birds would get chased out and not know where their home was, so the first option seemed best. Maybe there is another option to think through? Thanks in advance for your advice.
