I lost some last year when it was over 110+ degrees. We were in a major drought. What’s your humidity like? I think the humidity makes it tougher on them.
Not too worrisome. Especially during the summer (part of the reason why we get crazy wildfires each year). I will say that down in the coops it is a little more humid, but I intend to put them (IF I ever get them) in the less humid coop I have, which happens to be my main coop
