Very nice to meet you Adria. Welcome to Backyard chickens. Roosters can handle 10 hens, I hope you will consider getting several more hens, otherwise he will severely overbreed and possibly kill your one hen. If you do not desire fertile eggs to sell or hatch, hens are quite happy without a rooster. They will continue to lay just as many eggs but won't be abused or over stressed .
