My dad used to raise so many show-pigeons. He had so many trophies, we had to give some away to the neighbour kids. They were well taken care of, and had a special heater in the coop on those cold, snowy nights. When they flew away, they'd always come back (Though one did just sit on the roof and wouldn't come down for the longest while time.)

Then, one day, somehow, a raccoon wandered into the pigeon coop and killed and/or eaten them all.
