To WendyGeisler.....your set up looks pretty cool!! Great ideas!! Where did you get your hail netting?
We have a couple of evergreen trees in our run that the pullets have been staying under during the day, so they have been ok. I have been putting ice cubes in their water and giving them lots of very moist kitchen scraps. One of them, don't know which one has pretty dry stools. They all know how to drink from the chicken nipple waterer so not sure how to encourage them to drink more. Like some of you said, we water their yard at night to encourage the grass to grow and it tends to keep it cooler during the day. Today seems much cooler but windy. We put a tarp on one side of the coop that shades the inside of the a frame..the roost is over the 10 x 4 base of the coop and that also gives them some relief from the heat.
We are looking for a chicken sitter on the east side of town out by powers and barnes just so we can go away overnight sometimes and in October we have a trip planned to Washington for at least a week so need to find someone dependable. We have a good fence around our back yard but don't want to leave the girls door open at night just in case.
So sorry for those of you who have lost birds. It was traumatic enough having to find a home for our roo.
Take care out there...
