So I've got these chicks I'm raising, and they came with a big 50lb bag of "chick crumble", which is nice. However, the crumble is just that: crumbled up
something that chicks like and that's good for them. The point is there's lots of dust and lots of chunks too big for the chicks to peck and eat. If I just give them the crumble like that nearly 2/3rds of it gets wasted!
Instead, I pass the crumble through a colander and then a strainer to separate the dust and big chunks from the portion that is "just right" for the birds. I use the dust to
feed mealworms or put some on a dish and sprinkle some
water on it as a treat for the chicks, and the big chunks go in an airtight container for when the birds get bigger, or I can crumble them smaller if need be.
It takes a little extra work but it extends the feed, so to speak.
