I'm a client of Dr Rosenthal
Dr Ivey is no longer at that location. I only know because I refered someone there...
I would say its a younger one due to the beak length, toe nail length and the wings in comparison to the tail...but then its just a guess..hard to tell by pictures...
I've had babies who were plucked on their heads by their over preening mommy. she had to be removed...and because the folicles were not destroyed, they grew back fine.
Ellen has given some wonderful advice. She does need some darkeness to sleep.........
the most important thing is to have her looked at for the vet to advise just how to go about things, and if, its a youngin or older, and the warmth issues....
If you want, you can pm me where your located exactly and I can tell you which vet is the best, and closest to you. I've been in Jersey for most of my life, and know most of them on a first hand basis.
and Ellen, your welcome. thanks for bringing it my attention!
