It hit 100 degrees here today, and I checked on the chicken tractor, found the girls stressed, so I opened the nexting box door for better air flow, and to let some birds out. One chicken was really bad off because another bird was sitting on her. I pulled her out, got some water on her. She was conscious, but lying down. I kept putting more water on until she no longer felt hot, then I brought her in the air conditioned house, being careful to wrap her lightly in a towel. She is standing now, but is still very quiet, which is not like her breed (a Production Red, I think. These hens were given to us in exchange for a dairy goat buck.) I ran a sprinkler on the tractor for a little while to cool the flock further. All the other girls are out and about in the garden, now that we have some cloud cover, but is there anything to do for the stricken hen? When I nearly lost a dog to heat stroke, the vet had me give her sugar water afterward, and she perked up. Do I need to do this? She did drink some water for me. I intend to make her a private pen until she recovers so her chicken tractor mates don't pick on her.
