Medicated feed to chicks who have already been off of it. Is it an issues?

I recently had a family emergency which brought me out of the US suddenly and was not prepaired for it feed wise for my birds. My roommate took care of them for me but I ran out of food while away and he bought medicated chick starter by accident. Will the 1 50lb bag of medicated started cause any issues for my birds?

No worries, they'll be fine. It just contains a thiamine blocker so shouldn't create any issues. Just use it up and then go back to regular food.
Congrats for having someone close to care for your flock while you're away.
