Well i made a feeder so they always have food but im worried that they might get too fat because ive seen alot of rouen ducks that are really fat and that theyre whole body drags on the ground
You have standard rouens . Production rouens are the ones that stay thin . Your ducks need to get larger or there could be some concern . He needs to eat more than he is getting becuase believe it or not the rouens with the kneel that you see hanging from their stomach is a healthier bird than yours. So I wouldn't worry about him over eating he is honestly just trying to nourish himself becuase he isn't getting enough nutrition to fit his body .
