Entered the aviary this morning, and was greeted warmly by my two lutino cockatiels, Kawaii and Utsukushi. Kawaii seemed reluctant to fly up onto my shoulder for some reason, so I bent down to pick her up. To my horror I noticed there was a big streak of dried blood down her wing. After googling profusely, I found that it was a broken blood feather, most likely from night frights. The bleeding has stopped, but what do I do? Apparently i should pull the feather, but what tool do I use, and how do I minimise the pain for my poor little girlie? Thanks y'all!
