Hello everyone, I'm a first timer raising chickens. I got my first three chicks (Barred Rock) at the feed store over the weekend. They will be 1 week old tomorrow (2/25). I bought a bag of organic soy-free chick crumbles at the feed store where I bought them… It's huge. 40 lbs maybe? That's just a guess, but it's a HUGE bag. I didn't realize how little they eat and the feed store didn't have a smaller bag in that variety. How long do chicks stay on crumbles? When they reach an age where they need regular chicken food can I mix the crumbles in so they don't go to waste? Or maybe seal the bag up and put it in the garage until next year when I get more chicks… will it stay good? Thanks for any words of wisdom you have for me!
