Thanks for the replies. I've tried emailing the breeder in the Netherlands so will wait to see if I hear back. I've also left a message for the local pigeon fancier so, again, I'm waiting at the moment. I've currently got the pigeon in a cage in a quiet room indoors - he's got wild bird food and water and I'm fairly sure he's drinking a little. Is there anything else I should be doing for him to keep him comfortable?
