Thank you for replying with descriptions. I'm leaning towards heat stroke.She stays in an outdoor coop with a flock mate she gets along with so she’s not lonely.
while the other 4 are in the outdoor run.
Food: organic layer feed pellets she used to love, wet or dry.
Treats: it’s by the brand flock party and it has black sunflower seeds, and a few other grains. I give her about a tablespoon a day as she won’t eat mash or pellets.
The coop is large for just the two birds. It has 3 sides ventilated with hardware cloth
We live in central tx and it’s been 104-106 everyday with heat index of probably 110 ish. Two water changes daily to keep the water temps cool enough for them. Frozen water bottles for them to stand on to keep cool.
I would say it’s been about 10 days of her wanting to plop down and just sit down. She eats like that too if she’s standing for too long to eat or drink. She still preens, but she’s not herself at all.
