The temp is starting to get up there here too finally. They are getting frozen treats on the hot days. I mix fruits and veggies (and a few mealworms) with water and freeze then give it to them. They love it. I also started adding electrolytes to their water again. I'll change to apple cider vinegar once the temp comes back down. I am thinking of getting them a fan but the wind blows a lot here and while they are pretty sheltered they do still get a breeze and they have lots of shade.
I do have the fake owl that is "watching" my garden but he hasn't stopped the rabbits from chewing their way in and eating everything so maybe I should move him to the top of the chicken coop.
I have legbars too and you're right those little butts will fly right out if you're not careful. Our coop and run are covered with wire but we have a "forage run" as we call it that goes around the normal run and coop that we let them out in during the day and it isn't covered. The rest of the chickens (except the ee's) I don't really worry about trying to fly out but I do with the legbars! They are so entertaining though, I just love them!!
Oh yea I thought I'd throw this out here and see what you all thought. Somebody recently told me that you can purchase dog urine and have the people watching your chickens spray this outside the coop before they leave at night. With us our dogs mark the perimeter every day but when we are gone they go with us so this doesn't happen. I can't help but think that if you can indeed buy dog urine (not sure how they obtain it)

but it seems like it might help. Keep predators thinking that there still is a dog home??? Anybody ever heard of this??
