We have two Jumbo Pekins, Genghis and Kublai. They are a week old now. For the past couple of days, we've been noticing a lot of preening on Kublai's end. Mainly on the tail and naval area. He pulled off his baby scab a few days ago, and he's plucked his butt almost bald. Genghis doesn't preen as frantically as his brother does. Should I be at all concerned? We assume that it's just new feathers coming in, but we wanted to be absolutely positive. (It is a lot worse when he's wet, but that's the best picture the little bug would allow me to take) Our adorable little blurs. I've worked very closely with adult birds and I know that at times, plucking can be a problem when stress induced. Like I said, just making sure that this is normal.
