I am planning to get a pair or trio of Sebright bantams this spring to use for showmanship and maybe breed. I have a cage like this one: It is approximately 6 square feet, and I have it in a sunny, secure portion in our barn. Will this be sufficient to keep Sebrights in until June, when I can build a coop? I will, of course, bring them out for free range, and I have a larger pen they can stay in during the day. I just need something secure for night or when I am away. What do you all keep your banties in?
