Black spots on Canary baby skin!

Hi, I have a red factor baby canary (maybe a boy) born on 25th Nov 2011 and I've just noticed that he has black spots on his skin where feathers used to be... there's a clump missing from his back and the spots are from his neck to tail on the back and on the sides of his body but mostly at the back. Is this a serious problem? He seems fine, eats regularly... not fluffed up unless sleeping...

I know his mother rips out a few feathers but there's too many black dots for that to be the case... they're not all over his body but its still quite alarming... :(
