We don't believe in criticism on here, Joey, we all make too many mistakes! anyway, a big welcome to the Forum!
You don't have to keep a male unless you want to get fertile eggs for hatching (and if you do want to hatch,there are plenty of good sources where you can buy hatching eggs, which would have the advantage of not being related to your present hens so you could crossbreed them if you wanted.) Male coturnix (I expect they're coturnix, are they?) are often notoriously aggressive when in breeding condition, and have no finesse whatsoever in their mating habits. The two he's pecking may actually be his favourites if they are bearing the brunt of his attentions, and if blood is being drawn you will have to remove them, clean them up, and spray the injured parts with purple antiseptic spray for cage birds, which you can buy from a pet shop or similar place. Then keep them separate until they are fully healed, because just like chickens, quail are always attracted by blood and will pile in and make things worse. Injured quail usually recover and feather up remarkably fast, but the problem is likely to recur if you put them back with the male, and meanwhile the other two girls will have to take the brunt.
I was in a similar situation a few weeks ago and I culled the offending male. Your girls will probably lay better without him, as they won't be chased and terrorised all the time and will have more energy for eggs. The decision is up to you, but if you don't want to breed from him, and want your girls to have a peaceful life, you might reflect that he won't get any better. Culling quail is unpleasant, of course, but you have to be prepared to do it sometimes if you can't rehome all your spare males. Not all m ales are aggressive, I've got a pair in a cage together, left over from last year (long story involving the nasty male who is no longer with us) and he's so sweet with her, very protective, and I think that, unusually, she may even be going to sit on her clutch of eggs, which would be lovely. Do let us know how you get on.
