MOLTING
PARTS OF A FEATHERS
- Calamus – root of the
feather - Rachis – long quill or shaft
to give rigidity - Barbs – Extending from the
quill - Barbules – extending from
the barbs - Barbicels – extending from
the barbules
Could this be accompanied by a slowing down of laying, or even a complete halt
MOLTING
A change from down to juvenile plumage
(6-8 days to 4 weeks)

eyelids), ears, earlobes,
wattles and beak.
