Chicken isolating/ not herself

[deecooper]

Have a sweet 1 yr old Cinnamon Queen that has started isolating herself from the others and her comb is a bit floppy. Can see no signs of coughing or other issues. We are in the middle of a serious heat wave so keeping water fresh
and the they have plenty of shade. Giving them frozen watermelon etc for cool snacks. Just don’t know what to think. All other chickens are fine.
Any ideas?

Do you know that she is drinking? I have had hens just refuse to drink in heat waves. Combs turned purple and shriveled. I now filter the water I give them, and if any start looking dehydrated I taste the water. They can get pretty picky when its hot.
