Hi this is urgent , my lovebird who is 1 year old just appeared to have some random yellow feathers between his green feathers on his back , he is a Fischer so I found that so weird ! Plus he is over weighted. His diet contains seeds mostly and during the day he eats vegetables and fruits , I remember when his partner was a bit sick I offered them egg (the white part of it only ) I believe he has eaten too much of it , I've searched the web and mostly it says fatty liver can cause that I'm not sure I'd like to know your answer thank you so much
