I feel like a terrible bird mom, but somehow Perry got butter on her rump feathers and on her left side by her leg. I won't go into all the reasons I can't make sense of it, but to sum up, I didn't see it happen, it's not in a spot she's particularly curious about, and she's never alone out of her cage for longer than about 45 seconds...and always ALWAYS goes to her cage when she is left for those few seconds. Anyway, she doesn't let me hold her in that controllable way on her back to let me clean off her feathers. I've done my best to spritz her (which she has never enjoyed), but water isn't helping. It's not so much that she's having trouble flying or anything, but obviously I still want to clean it off of her. Any suggestions are welcome. Any chance it's ok to let it be and she can safely get it off herself eventually with preening? I'm a little concerned because it's butter and they can't have dairy, but it's not like she's biting off a chunk and eating it. I just don't know what I can do, because I may have been trying too hard now, and she's very suspicious of me at this point even just asking her to step up.
