So, working in HVAC, you probably know all or most of these tricks, but I'll share just in case, (note, I don't know how humid it is where you are - some don't work as well with high humidity)
A) Spray roof of coop (or roof of run, if you have a solid roof) with water from hose.
B) Hang shade cloth over area near coop to help lower temps under cloth and around coop in general.
C) Dampen ground in a shady area for them to dust bath in cool
er, moist soil.
D) put ice in their water...and have a shallow dish they can 'wade in' to cool their feet.
E) Give them a block of ice in a quiet shady area they can lay near to cool off. I freeze gallon jugs of water just for this purpose in the summer. (
Note, on really miserable days, I 'bury' a 20 oz. soda bottle, with frozen h2o in it, in their favorite nesting boxes. I slide it into an old sock to slow melting and to soak up condensation)
F) and, of course, frozen treats and/or chunks of ice with treats frozen in them.
G) (only if dry where you are) Mister high up to help cool area.
I didn't mention fan since you stated you are already deploying that. I will say that I started using shade cloths 2 years ago and they make much more of a difference than I expected.
Also, a longer term solution would be to plant a bush/tree/climbing vine in strategic location near coop.
Again, you probably know all or most of these strategies...but thought I'd mention them just in case.
I'm sooooo glad you found her in time!







That would have been a horrible loss..the poor girl!
