I have a sick bird

[Gypsy Rose]

My girl was tripping last week. I noticed her crouching after the roo mounted her. She always seemed to recover. She did it a couple more times and I held her on my knees on her back and checked her feet, legs, vent and crop. All over and she seemed fine. Yesterday I found her standing in the ice bath. I put it in the coop because it's 115 degrees. I picked her up and put her down to.get a treat and she couldn't stand up. Shes isolated I've been giving her poly visol one drop per day. B12 in the water shared water ever since I saw her stumble. Thinking maybe that would work. What could be wrong and how do I treat her

How old is she?

When was her last egg?

She may be suffering from heat exhaustion. I'd give her electrolytes or a little sugar water.
She may benefit from being placed somewhere a little cooler as well.

If you need to leave her with the flock, then move the rooster for several days until she recovers.
