I have two hens. They do everything together, yesterday I was out with them while they were in the yard doing chicken stuff, and then it was time to get back in the run - so, they were eating their mash together (of course) then stopped to get a drink, as I was watching them, one stopped drinking to look around and the other one noticed Ruby had food powder all down her front, so she (Pearl Anne) decided to nibble the food gently from the other's feathers, they did this in such a loving manner I almost wanted to scream! Just had to share. Never knew chickens could be SO SWEET.
