When it's raining, all my girls go get a drink outve my easter egger's wet beard. They'll walk straight past the drinker to get to that wet beard that usually has a fair bit of dirt included by then. The easter egger who wouldn't win any prizes for tolerance usually doesn't actually seem to mind becoming the drinker when it rains. Also, my brahmas walk past the drinker to get to my car if its been raining to peck all the little drops of water. Luckily they don't peck hard enough to do any damage. What kind of different drinks do your chickens like to have?
