It got to 104 in the coop today. And it's in total shade. I had 2 fans and a mister going in the run, I hope that kept the temperature under 100 in the run during the really hot part of the day. I don't have a thermometer that will hold the high and low in the run. I only have 3 silkies, they laid 2 eggs yesterday, none today. They look OK so far. I looked up outdoor air-conditioners on-line. I found one for dog houses for $600.00. Seems like a lot of money for 3 chickens. I hate worrying about them in this heat.
I've been hosing my chicken's area down thru out the day, especially under their favorite tree..using a fan... Frozen water bottles in their water giving them frozen berries in a little bit of water for daily treats at the hottest time of the day.... If i could afford an outdoor ac i'd probably get it .... But my girls (silkies, ans sizzle, polish, and barredrock) seem to be doing good. The day it got to 108 i even went out and misted them til they were a lil wet... They didnt like that too much.. ( in the pocess of getting a mister) but they do like playing in the cool moist dirt (out in the garden)
