they guy at the feed store not very helpful told me they were between 1 day to a little over week and the typs where on teh wall but the pics where of adult chickens not peeps
They're very cute! Some of the hatcheries show pictures of the chicks as well as the adult birds. Maybe you could find out which hatchery the store bought them from and then check that website? Murray McMurray seems to show chicks with the adults. I'd think your cute chicks with black would be easier to identify than the yellow one. Good luck!
