I have a cornish X pullet isolated in a wire dog crate, within the coop. One of the little cups that hook onto the side of the crate for food and water had a broken clip, so I brought it into the house to fix it. Put it back on the door of the crate and filled it with water from a cup. All of the other CXs came running to try and get a drink of water from the cup, through the bars of the crate... ...with their five gallon waterer full of fresh water not two feet away. That is today's definition of a dumb chicken. Cornish Xs - sweet as pie, dumb as a box of rocks.
