Hi my son's bday is just around the corner and he wants chickens (well he wanted a horse but WOW EXPENSIVE LOL) anyways I'm just wondering here at tsc they have chain link dog runs. Cheaper than coops and there bigger would that work? And does 6 sound like a good number for the chickens. I'm sure he's committed to this he currently has 2 alpine female goats and he spoils them and 1 rooster that insists he need feed costing $17 a bag lol
