I noticed today that my Leghorn rooster's beautiful tail feathers are a bit ratty looking. Not missing, poopy or broken in any way, just not as nice & smooth as they normally are. He's been at the county fair for a few days, and was cooped up in a display cage, plus the transfer to a pet carrier there & back, so I'm thinking that's the culprit. So how can I get them nice & smooth again?
