My two Rhode Island reds are a month and a half old and i ran out of their Manna Pro medicated started feed and told my dad to go to tractor supply to buy them more. Instead of buying them more medicated feed like I asked (considering their 8 months of needing chick feed isn't up yet) he bought them Manna Pro Gamebird/Showbird feed. They are being raised as show birds but im not sure if they should start eating that feed yet. Is it ok for them to eat that yet? Or should I ask my dad to exchange it for medicated feed? The picture below is how big each of them are.
