First step is to treat him for shock with some electrolytes and a little sugar water—Gatorade will work. Then wait for more experienced advice. I had a hen attacked by a raccoon that was trying to bite her head off and although I couldn’t see any physical injuries she was never quite the same. I...
Gotcha. I get distracted easily lol. I would give it a try supervised for a couple hours and see how it goes. Do you have some clutter in your run for the younger ones to get behind if they need to?

Those little cups that attach to the side of a cage work great. They’re designed for birds or travel in kennels I think and hold about a cup worth. You can clip it to the side of their run just make sure it’s covered so the oyster shell doesn’t get wet and start dissolving
I should ad that I feed two different brands of chick starter, one of which is a mash that I ferment. The other is a crumble I feed as is. The fermented stuff actually has grit in it so I do provide grit in that sense but I don’t think adult birds need it added to their food—it’s probably...
Put the oyster shell in a separate dish and grit in another. Don’t mix them—they will just get wasted. I don’t provide grit for my chickens because they can find it themselves out in their free range time. I can’t answer about quail so hopefully someone else chimes in about that
The Delaware shouldn’t have all that black leakage (?) either. Maybe a hatchery quality issue I don’t know enough about them. I had a couple but one of mine confused me right up until she laid an egg
