How do I help my girls manage the heat? They have constant access to water, and I've been putting ice in it. I've tried to give them cool treats like chilled grapes and watermelon, but they don't seem to like them. We've only had them since Saturday, and the heat is oppressive this week. Tomorrow, it's supposed to cool off to the low 90s. They are panting and walking around with their wings out. Can I run the sprinkler on them?
