Wooo I found some local Oxbow pellets and hay, well local being a relative term...its just over an hour away

And so I am going to be switching form Mazuri 5664 to the Oxbow Cavy Cuisine. Right now I have almost 2, 1 gallon freezer bags of my Mazuri left, one in the deep freeze and one I just opened and am using. The thing is should I get the Oxbow right away after "looseing" or "droping" the remainder of the Mazuri or should I keep some Mazuri to mix with the new? Anyone have probs getting their pigs to eat Oxbow. Also I am thinking of maybe keep feeding the Mazuri and Oxbow both, I was thinking about mixing them so it'd be half Mazuri and half Oxbow, they'd still only get 1/8 cup each of the mix. they'd be getting 1/16 th of a cup of Oxbow and 1/16 th of a cup of Mazuri 5664 would this be okay? I was thinking of doing it to save money becuase I get the Mazuri 5664 super cheap and close but the Oxbow is over an hour away and after how ever much it costs (I was so excited I forgot to ask

) but I have a feeling it'll be alot because its from a vet office, plus gas money it'll be getting pretty costly. Would mixing them be okay? I'm pretty sure it would be I just though I'd ask.
