I have a fan in my banty coop since they aren't under the big shade tree like the biggies. They are all standing in front of it. I turn the hose on every few hours for the big girls so they can stand in it for a few minutes but tomorrow they are on their own. We have a BIG bush in the middle of the chicken area and they all huddle under there when it gets hot. I traded off most of my fat chickens so have a lot of naked necks and leghorns now - my big worry is all the broodies. Have a fan on them but they won't get up to get water even if it's in front of them. silly girls.
