You can get lifelytes at the feed stores. It is vitamins and electrolytes. Mix it up and put some ice in there for the hot days. You can give her some to see if that helps her get back to normal. Good luck and .
did you find some help for your pullet? Is she doing better? I brought my rooster into the house and had to give him water to drink and I tried to feed him cold things like grapes and watermellon. I put him back in the coop that night and he was much better the next day.
My roo really suffered this afternoon. I went to check on everyone and he would not move. I cooled him off with the hose and got him to drink a little. He is now inside and working to get his feet back under him.
