Hi All, I have 10 young girls (2 Buff Orpingtons, 2 Lavendar Orpingtons, 2 Ameraucanas, 2 Barred Rock Plymouths, and 2 New Hampshire Reds) which I selected because of their Heat/Cold tolerances and their gentleness and who are supposed to start laying in the next couples of weeks. I go out every day and put large ice into their waterers (think Dixie Cups when we were younger but not flavored - just water that I have frozen). I give them slices of frozen watermelon, peas, corn, carrots, green beans) as well as chilled treats. I live in what is known as the high desert - above 4,500 ft but hot, dry, sometimes very windy....dry...dry...dry! Average humidity is about 30-35%...not much at all. Anyway, I see all of my girls panting - mouths agape - and holding their wings out a bit away from their bodies. I have a covered integrated coop and run with nesting box on the east side. I am worried and am considering buying one of those portable misting systems that you hook up to a garden hose and use it to help cool them down. I found this one on Amazon...https://www.amazon.com/dp/B004INGNPG/?tag=backy-20 Anyway, I am a newbie and want to know if I am over-reacting? Also, I have them on grower feed and think I am supposed to covert over to layer feed ONCE they start laying...is that true or should I be giving them layer feed now knowing they will be laying soon? Most importantly, is their behavior normal? Mouths open, wings slightly opened away from their bodies?
