My husband got up in the middle of last night, to the sounds of chickens clucking like mad and the dog barking her head off. He got out into the yard and saw a white bird, about the size of a medium chicken, perched on a pole. As soon as my husband attempted to get close, it flew off. What do you think that was, and what should we do about it, if anything? My only possible guess is an albino owl (we're much too far south to suspect a snowy owl...). Any other guesses?
