They are outside in a large 42"dog crate without the tray in the bottom so they can eat grass and bugs. They have water, food, and plenty of grass. Half of the crate has a tarp over it so that there is some shade. They have two roosts. There are 5 guineas in with 3 seven week old chickens. It is 100 degrees outside and they appear to be panting. Should I put ice in their water or cover them completely or add a fan or just let them learn to deal? Thank you!
