Hi everyone. This is my first post. I have 8 hens and one rooster that have been together for about a year. From this year's incubator and broody hen experiment, I have 8 hens and 1 rooster that are 4 months old. I would like to merge them into the existing flock if possible. Given the size of my flock, how many hens and/or rooster can I introduce at one time? Do it all at once or a few at a time? All the birds are about the same size (no small or exotic breeds). There is plenty of room available in the coop and the yard, so space is not a limitation. I've read all the posts I can find about methods to introduce chickens and roosters, but couldn't find anything about how many birds you could introduce at one time. I'm prepared to create a separate flock if I have too, but wanted to get some opinions about "a big merger" first.
