Making bacon brown sugar scones, can I sub dried onion for chives?

My recipe calls for 2 Tbsp chives. How much dried onion should I sub? I don't use it much but I bought a jar of supposed better quality stuff at costco not long ago for my roommate who likes it. I also need to hydrate it I suppose. Put it in the milk a while before mixing?

Sorry all the stupid questions today but I am a bit frantic. Also the site is acting up because I am only pressing the "ask now button once"
