Egg Laying and Approximate Age?

[Banaynaychicken]

I recently adopted 7 chickens, 4 Barred Rocks, 2 silkies, and a Gold Laced Wynadotte. Unfortunatley, I was not given the age of the 2 older Barred Rocks, and Silkies. Could anyone help me figure it out? Ive got pictures of the chickens to help maybe identify their age. I would guess the barred rocks are 16 and 17 weeks old, but I cant be sure.



This is Yukon, she is the older of the 2 silkies, I would say by about a week and a half older than Nugget.


This is Pollito, and she is about a week older than my other Barred rock.



This lil chicken is Nugget. I need to know all of these chickens ages, so I can determine when they will begin laying eggs

I have barred rocks too, so I'd say that Pollito is maybe 3 months, hard to tell from the picture. They can lay on the 17th week, that is when ours layed. I dont know about the rest. Sorry.
