I've had my White-winged parakeet for just over a year now and we have bonded really well. He spends nearly every moment we are together on my shoulder. Lately it's becoming a problem because his nails have started to grow really sharp and its kind of painful having him there. I have tried trimming them myself but I'm no expert and he gets really upset when I do it so I usually limit it to 1 or 2 nails per day. I was looking into those sandy perches that supposedly trim their nails whenever they're perching on them but I've read that they can irritate their feet so that has left me weary of them. What do you guys suggest I do?
