New chickens & new coop

We just adopted six hens from friends of ours and they gave us their large coop as well. We already had two hens and a very feisty rooster in a smaller coop. The large coop is in our back yard and the small coop is in our front yard. How do I get my three to move to the new coop in the back?? The hens would let me pick them up if I can get the rooster away from them. But he will not let me that close to him. Also, do I need to worry about my three not getting along with the new six? Any advice & help would be greatly appreciated!!!

Anything?

You could try a fishing net to catch the rooster. Or get him off the roost at night.

Do roosters tend to be a bit nicer if taken off the roost at night? He used to let me do that but it's been a while since I've needed to and he's gotten very sassy in that time.

Chickens can be easier to handle at night.

Thank you! I'm gonna give it a shot.

Holding the birds wings down against their bodies should make it a piece of cake to move them when they are sleeping.
Keep wings restrained and don't let their feet gain purchase on anything.

But......putting your existing birds into the new coop with the new birds at night could make for a chaotic, and possibly bloody, morning.
Do your birds free range at all?
Is your new coop really big enough for all the birds that will live there?

Yes the old ones free range. I haven't let the new ones out of the run yet cuz we just got them on Sunday. Yes the new coop is really big!!!

Should I let them all free range the yard before putting the old ones in with the new?

First I would move the one coop to the back so the two flocks can see each other.
Second I would let the flocks free range together. There may or may not be squabbles but in a free range situation the one who loses can escape, in a coop situation they are trapped.
Third I would let them roost where they want for awhile and then transfer the birds from the coop you don't want them in to the coop you do. If there is no hurry to combine them I would give it a week or two.

I will tell you it is not easy getting chickens to rehome to a new coop. I built a new coop and tore down the old one. The old one was not removed immediately but was left in a pile where it once stood. Until it was completely removed the chickens went and tried to roost on top of the debris every night. I had to move them one by one to the new coop.

Also, five years ago this month I was hit by a tornado and the chicken coop had a tree split it in two pieces. My garden shed survived. So temp. I had to convert the garden shed into a chicken coop. Again the chickens went back to their old coop every night to roost. They did this until I could get the destroyed chicken coop off the property. That was a total pain in my butt. It was not easy for me to get in and out of the destroyed coop. It was easy for the birds but not so much for their owner.
