Nope, no chickens in the truck, they tend to be a bit "messy" and I go to some very high security places that don't allow pets of any kind.
One H/W team do keep a small Cockatiel with them. He has a perch on the dash and rides just like he belongs there.
We did bring a small RIR in the house to mend after an attack by a fox, other than the poop she wasn't much different than a cat. She would explore and eventually hop into your lap and preen, for some reason I really enjoyed it.
One night she was on the couch with us and kept eyeballing the ceiling fan (it was off) for about ten minutes. All of a sudden she flew up and roosted on top of the fan, hilarious. I surmised since it was night she was looking for a roost to sleep. We took the shower curtain down and put just the rod back up, worked perfect for her roost. She's now back out with the flock doing chicken stuff. Call me crazy, but there was bond created when my GF brought her in and nursed her. When she hears or sees Karen she's right there and has no problem being picked up. Kinda miss her in the house, always provided a good laugh with her antics.
