The last two days we have had a heatwave where I live. Temps around 106-111 degrees. Chickens have had plenty of shade and water, but yesterday I went out and found one of my hens not looking good. She is panting and her comb is a dark color. I have removed her from the pen incase she is contagious. Any idea what can be wrong with her and what can I do about it. Any home remedies??
