So, a few days ago, the tip of Yei's tail feathers started turning pinkish, and I put it down to the pink seashell claw trimming perch in the cage. But then, today I noticed the tips of his/her wings were pinkish too. Yeti seems to be in otherwise perfect health and doesn't fluff up except when sleepy, but I know budgies hide illness very well.
Does anyone have any ideas? Pictures are attached
