I had a small quail who lived alone then one day a patridge turned up in my garden and wouldnt leave i picked him up and put him with my quail even though he was much bigger but they got on along just fine and they were in a small house so a big run should be good for them
My peafowl and chicken live in a big enclosure together and get along perfect. They also live with rabbits. The peacock will try to scare of cats and rats for the other animals. My peafowl dont pick on any of the chicken or fight my rooster. Also i had chicks and the peacock looked after them well.
I brought a peacock from a farm of 2 peacocks and 1 peahen and i got my peahen from another farm with loads of peacocks and at both farms they got along well and so are mine now they both sleep by each other and take care of the other animals
It shouldnt matter on the breed of the rooster as long as its not an aseel one as they fight different species of chicken so i hear but u should probably get one around the same age of ure hens
Roosters are great ive got 1 and he really takes care of my hens peafowl and rabbits. He stands out of the hens and makes my flock more colourful
You should get more then 1
Last year my rooster and 1 of my hans got 3 chicks
