What is the best way to get rid of pigeons in a barn?
Answers:
Patch up all the holes that they can get in/out through firstly. Then get some cats. Or a BB gun (nothing larger, as you'll shoot holes in your roof).I think that you will find that more humane methods are sadly, either quite costly, or are quite hard to do, and will likely be unsuccessful.

put up a stuffed owl in the rafters. get one that flapps its wings. scares the heck out of them.

Owls.
Put wooden owls at all the entrances. Works on my balcony!
Get 1 or 2 cats.
I'll rent you my cat; she gets, on average, 2 or 3 pigeons from my yard each week. :)
