first time racking to secondary...got a question

[sputnam]

before i started brewing, i did a bit of research and decided i wasn't going to do a secondary. now i want to make a bourbon oak beer with oak cubes and i feel like a secondary is kinda needed. my question is if i'm planning on a 2 month secondary and there is no active fermentation, what will keep oxygen off my beer?

There's a fair amount of CO2 still dissolved in your beer after primary. Racking it over to a new carboy will get some out of solution. As long as you have as little headspace as possible in the secondary, you'll be fine.
