Hi everyone. We have a 9 weeks old muscovy duck and today we are planning to buy him a bag of food. He was eating a Chick Starter by Manna Pro (non medicated). Do we still have to feed him with starter? Or we should switch to Grower? In that case, which are the best options? He is an indoor / outdoor duck. At night he sleeps in his petcarrier inside the house until we finish his coop. Any help will be appreciated!!! We are very new in this duck thing. We rescued him when he was like 1 - 2 weeks.
