I will get them some mealwormsSure they can eat the mealworms. Dried ones are fine. They tend to crumble a little anyway.
Ash if you were closer I would give you some chicks for free to replace your roosters. I have several broody raised chicks and several barred rock babies I could part with.

Yeah, 2 1/2 hours is a bit far away

When and if they do turn out to be roosters, should the new ones we get be around the same age? I wonder how hard thats going to be to do?
