I decided to give my 6 week old white leghorns a treat so I threw some Pennington wild bird feed on the ground (minus the sunflower seeds) and they wouldn't eat it. Ok, a few days later I threw some salad lettuce mix on the ground and they wouldn't eat it either but they did run over real quick to inspect what I threw down and picked at it for a minute then walked away.
Is this normal? I thought they like to eat about anything.

They are still quite young. They are probably more interested in their crumbles. Maybe try meal worms. I give a scratch grain mix with BOSS and rolled oats. At first they inspected and ignored it but then one would start pecking at it then another would. Eventually they figured out that this was good stuff. I did put some chick grit in their feeder with their feed so they have access to some grit. They are not to keen on the greens. My older birds love the greens.
