My chicken yard was adopted as a temporary home to someone's pet pigeon during the strong winds of the past couple days. He would eat whatever dry food was on the ground and the seeds I scattered for him before releasing the chickens in the morning, and occasionally grab a drink of water when the chickens weren't too close. Other than that, he just sat around, walked around and tried not to get blown away. He flew off last night, returned this morning, and then flew off again tonight. I'm hoping he finds his way home, but if not I'll try to catch him and track down the owner based on the numbers on his leg bands.
He was so lucky he ended up in your yard. I hope he gets home. Thank you for looking out for him!
