Hmmmm well isn't the point of a grazing box to limit what they have access to? Like they only eat what can grow up to where they can reach. So would it still be too much?
I would think them foraging and grazing themselves would be okay? I think treats would be more like kitchen scraps, scratch, tons of mealworms, corn, etc. but idk. Maybe grazing boxes still count as treats. Idk. But I would think with the really high protein feed it might be okay? I know tons of treats waters down the nutrition in chickens too so I have mine on an 18% layer instead of 16% so when they free range and get scraps it is still a good level instead of being too low protein. So maybe you could do a similar thing with the quail? Feed a higher protein than recommended so they still have a good amount of protein? Although quail are way smaller than chickens and already eat a lot less as it is so maybe the grazing is worse for them. Idk.
