It's over 90 and looking to stay that way for awhile. One of our hens hopped up and splashed around in the concrete birdbath out back, and it got me thinking: would the girls enjoy something larger, a small wading pool perhaps? I wouldn't expect them to use it to get clean (they seem to do fine with their dirt-baths), but to splash around and cool off? I don't want to waste a bunch of $$ if that's not something chickens "do." Thanks as always for any info!
