I have a small flock of 9 hens, and two roos. One of the roos has the 9 hens to himself and the other lives in the goats barn with the goats (of course) and the two ducks. I have had the hens and roo locked in the run for the past couple days since over the weekend, it seemed as if there had been a 'cock' fight between the boys. I am guessing the 'loner' roo has gotten tired have having no hens for himself. The had been free ranging together fine up until this point. So I found on Craigslist so full grown hens for $3 each. I have told the people that I would like 10, but I am starting to reconsider. I know that the other roo needs some ladies, but I am worried about adding to the flock. I have a dog pen next to the animal yard (I let the goats, chickens and ducks all hang out together in the same area) that I was considering putting the new girls and 'loner' roo in, but its that too close to the area I keep the old flock? The run is perpendicular to the dog run with the coop between. I am afraid of inviting trouble...germs, etc. Maybe start off with chicks again? I just don't know. Maybe I am over thinking? Advice, please!!
