My 6 Golden Comet hens have gone from drinking maybe a half gallon of water/day on the hottest days & suddenly their 2 Gal waterer has been dry the last couple of days. I filled it this AM. & just gathered eggs this afternoon & it was empty. My first thought was that it was leaking out, but there's no water in the deep litter where the waterer sits. Could they possibly be drinking that much water??? Here's those thirsty critters........ OBTW, that's not their current waterer in the pic! They now have a 2 Gal galvanized waterer.
