Roosters are pretty indiscriminate – a hen is a hen to them, and they’ll mount whoever they can catch. And most likely will fight amongst themselves eventually unless you plan on maintaing a large flock of hens, or penning them separately.

If you want a rooster of each breed, I would recommend placing them in breeding trios, where each rooster can have a couple of hens of their own breed in their own yard or little house. I’ve seen some pretty ingenious designs for creating individual trio houses.

If you let them all free range together, you will never know if your eggs are going to hatch out chicks of that specific breed, and with multiple roosters, each brood will most likely have DNA from every rooster. If you plan on breeding, it’s alot harder to sell chicks if the buyer can’t identify what the bird is.

Also, from my experience, araucana roosters tend to be very nice – and leghorn roosters can get very big and aggressive. If you are mixing different breeds, make sure your roosters are of similar sizes so everyone stands a fighting chance.

I recommend everyone who plans on owning chickens pick up a copy of Storey’s Guide to Raising Chickens – it’s a great reference source that any chicken owner will benefit from having. Get it at the feed store when you pick up your chicks!

No, any male will breed with any hen a roo is a roo, all chickens are the smae cromosomes and genetic, there just different colors and looks.

If you have one male with a couple hens they will breed, no matter what there breed is.

U can have a male of each kind, but eventually they will not get along, without hens there un happy.
