How old am I?

[INchickens]

I am extremely new to chickens...and learning as I go. I have no idea how old our chicks are. How old are they typically when the feed stores get them? We've had them since Easter (1-1/2) weeks. Any input would be appreciated. Also...they are picking at each other something terrible....I've tried a number of things to get them to stop as suggested in other posts but nothing is working....I finally had to take the black araucanas out which seemed to be the aggressive ones. Suggestions?

The amount of feathering on their backs look just like my three week old buff orpingtons.

I agree, about 3 weeks.

I'm not sure how old they are but they're adorable.

I am thinking 2 1/2 maybe 3 weeks

About a month.

I say they are just about 3 weeks old. They have wing feathers besides their primary and secondary feathers, and tail feathers coming in, but don't have adult feathers on their heads. If they start getting filled in on their heads, they will be closer to 4 weeks.
