hellow everyone! me (and my son) are new to BYC.we get alot of info from here so we decided to join.i have a 4 year old game hen that has a watery eye.gave her antibotics in water for two weeks,took her to the vet and she got a shot.funny thing is as long as she is isolated her eye looks fine.she never had a runny nose or rattle to her breathing.as soon as i put her back with the other chickens in the pen her eye starts to water agin???iv done this four times now same result.

If it waters only when the other the chickens are with her, they could be pecking at it.
