I agree, but there's a different between giving your old bread scraps to chickens, and purposely going out and collecting tons of it to give your chickens as their daily regular main source of food. There are plenty of different types of food waste that can be repurposed for feeding chickens. I generally say give them whatever's in your kitchen, and any other food scraps you can get your hands on, provided they're either moderately healthy OR part of a varied diet. But if you're going to seek out a single type of food to buy in bulk for the purpose of feeding your chickens, white bread is not worth it imho.
Yeah, and I think the answer lies in the middle. Feeding NO bread or very little is obviously not a problem (but doesn’t get rid of any/much stale bread). Feeding ONLY bread is a bad idea.
There’s a big range of “some bread” that people seem to ignore. If someone says “can I feed x to my chickens?” Folks here tend to jump to “feeding chickens ONLY X”. It’s crazy.
Yesterday I picked up some food waste for my flock. Probably 3 wheelbarrows full, or a tad less. There were a couple bags of stale bread in there. When I fed it, some of the flock went for the greens first, some for bread first, some fruit first. Nobody ate only one thing, everyone ate some of everything.
I consider that “food”, not treats. Feeding a chicken lettuce is NOT like feeding them candy, it’s like feeding them (or us) lettuce. It’s fine as you compensate for the nutrients that aren’t in lettuce.
