My flock loves bread, it's okay for them to have a slice between them 1X a week as a treat, But it is carbs and will make them fat so limit it to 1X a week only use it too get to know them better, sitting on the ground pinch off small pieces and toss to them gradually tossing closer and closer to you till you have taught them to eat out of your hand,may only take a few days make take longer so be patient. When my flock is out foraging and I want them to come to me I can go outside with a bag of bread and shake it they come running. I can also use dried mealworms in a empty coffee can and shake it and they come running, I also whistle so start training them to come either by whistling or calling something like come duckies time for treat. always give them a treat when they come and they will begin to associate you with something really cool. Best way to make friends with ducks is through their tummies.Okay bread is only 19 cents for live stock feed over here. so I will feed them maybe 1 piece between the 6 of them a week? Is that okay?
