You're right, I'm sure. Guess there's no avoiding it.No way to stop the big's from eating those crumbles once they are together. You may have to set up a few feed stations of the crumbles so that the chick's will still be able to eat without the big's chasing them away from food and water.
Since they're still separated for now, I did toss some pellets in the littles' food dish last evening. Curious to see if they eat any. (Haven't checked yet.)
