This is a terrible picture but the best of all I took. The bump is on the left side top of head. I didnt want to stress the poor thing out too much and so I got it right back out to the pen ASAP. The bump makes it look like it is a polish top but it is much more than feathers poofing up. Im really worried. This little one is also cross beaked but has been doing well. I did trim the beak once.
