@Nabiki that's reassuring! Put him out in the pigeon loft for the first time this morning, it's 4x4 and solid walls all around with ~3" of ventilation along the top 3/4 sides. He's got a ceramic heat lamp in one corner keeping it up to 93°F along with his cat toys and towel to snuggle with. He's yet to panic or show any such signs so I think we're off to a good start!
