My turn! How old are my chicks?

[3SiameseCats]

Got these girls last Saturday. Unsure of age.
Bramas:

Barred Rocks:

Buff Orpingtons:

 

[Rose the Legbar]

They look about a week to a week and a half old!

 

[3SiameseCats]

They look about a week to a week and a half old!

They had wing feathers when i took them home. Would a week and a half be a better estimate?

 

[SilverBirds]

The look to be 1-2 weeks old.
