I lost a hen this afternoon....to what I am assuming was the heat.? She was fine this morning, and was in the nest box, she even layed an egg....but when she hopped down, she collapsed...her comb and wadles ...purple then passed away. It has been extremely hot here, and high humidity. I have fans on them.....cool water with electrolytes....cool fresh fruit and veggies treats in the evening...and puddles to wade in. I really dont know about her poo, she is one of my 13 free range chickens. Does this sound like heat related??
