My husband and I are having so much fun with our chickens! We both work city jobs, but live in the outskirts of a metropolitan city, and so we have been raising female chickens for 2 years. (Give eggs to our family/friends, love on the chickens, etc. We haven't ever kept Roosters, (didn't want to offend the neighbors with noise), but when we purchased our new female chicks this year, you guessed it - one was a rooster. My question is this.......We have probably 7-9 different kinds of chickens. Barred Rocks, Crevecours, white leghorns, partridge cochins, RIR, 1 bantam and a couple of others. Our chickens are pets, we purchased for the variety. If we choose to keep this rooster, will he breed with all of them, and produce odd chicken breeds? We're new to this. Is it morally correct to breed only within the breed, or can/do you cross-breed? What happens when you cross - let's say, a white leghorn with a partridge chicken. What determines the breed? This may sound corny, but we're just learning, and this is the best site I've found to do that! Thanks for any advice!
