hey its brandon, i have 4 old english game bantam chicks, 2 boys and 2 girls. i really need to know how big they will grow, so i know how tall to make the new coop, if i can let them free range in the day etc, and what other bantams can they go with, to breed? (like my silkie hens?). Do you have pics with them next to you or in your hands etc? ANY HELP IS HANDY! thanks in advance.
