I'm concerned for my chickens during this HOT weather in the mid 90s and high humidity, and this weather is expected to last for several more weeks. Will my chickens be ok? What danger signs should I watch for? They have fresh water available and shade.. What else can I do? They're out free ranging during the day, in the coop at night.. I'm not able to add a fan to their coop. I have same question for my ducks too, but they get to swim all day, so I think they'll be fine.
