Lack of breast feathers on two of three 4 1/2 week old Canaries

I have two young Canaries which appear to have abnormal breast feather patterns (or lack thereof). One, which is the runt, is almost completely bare on its left side. The other has a bare patch on the upper right breast. The third has no visible defects and appears normal.
Is this a congenital defect? These are Red Factor Canaries.
The youngest is still being fed periodically by the father. I removed the hen thinking that she may be plucking them.

Canary babies lacking feathers

Parental trauma is possible. This can happen when trying to make the babies fledge or when there is over crowding. It could also be a nutritional problem or even genetic and congenital or may be related to the nest material. You should have them seen by an avian veterinarian.
