We're entering our first heat wave in Tennessee, and I'm worried about my flock. We have our chicken tractor in an area where there is absolutely no shade whatsoever. We have covered the tractor with a tarp to create shade for them, but I don't know if this helps or hurts because I worry about the air getting stagnant and stuffy in there. We try to make sure their waterer is full of cool water, and I add poultry electrolytes to it. I am also planning on freezing some water bottles for them to lean on and perhaps putting a little chicken swimming pool in their coop. Is this enough? I just worry because the summers here get so hot. Last year, I don't think the daily highs dropped below 90 degrees from July through August, and I'm concerned about my ladies. Thank you!
