I don't have cockatiels but this does look a bit strange to me. I don't know if this is from the sheath or what, but it does look as if she is having trouble getting the sheath off of the feather.55 Based on my reading cockatiels seem to develop feathers more readily than most other species and I am wondering if this might be an indication that her dietary needs are changing.
We have been breeding cockatiels, probably longer than any other species except for Budgies, which we have really messed up genetically speaking, but still there is very little to go on for older birds.
