I got a 2 level ferret cage from ferret nation on craigs list for the broody hens to feel air up their bums. The wire is nice and strong but maybe 1/2 inch by three inch spaces? I think their feet could get stuck? Is this ok or how to fix it? Please answer as I have 2 other sick chickens and two broodies and I have about had it with these damndable chickens. They are stressing me out.
