I fed Mazuri game bird feed to my quail while they were growing because I couldn’t find any game bird feed near me and I liked it a lot and it’s pretty high protein (they have a few different formulas some lower so you’d have to look. I think mine was starter) but the only downside is it’s pretty expensive online. I got it directly from their website because it was out of stock places but maybe it’s available somewhere else. Chewy carries it but idk if it’s back in stock yet. I’ve also found the Blueseal multi flock is pretty good. It’s like 23% I think instead of Flockraiser’s 20% so I like feeding it and it works for adult game birds too I think. I got it at my local Agway but idk if it’s online or what.
