Baby chicks lost breast feather/fluff?

[FC16]

I have 3 Silkie chicks which are about 4 weeks old.
I have just noticed that all 3 of them have lost the fluff/feathers on the front sort of breast area.
Is this normal? It’s gone completely bald?
I could have sworn that they weren’t like this this morning when they were being handled.

Unfortunately I can’t get pictures right now as it is dark and they are settled for the night

It's normal. New feathers are coming in and pushing out the baby down fluff. There are even several juvenile molts chicks go through before they reach four or five months old. Be ready for continual feather loss. It's normal for chicks.

Thankyou!

Just though I’d post a picture as I now have one

Adorable chick. Yeah, that's normal. Nothing to worry about.
