I didn't do a clear job on explaining the wood part. Here goes another shot :)
For chicken or fast smokes I go at least 50% of a strong wood. The other 50% could be anything else you want, strong or mild. I just recommend at least 50% of a strong wood at a minimum for your chicken smoke.
So you could do 100% Hickory if you like. Or 75% Hickory and 25% Apple, or 50% Hickory and 50% Maple, etc, etc. etc.
When doing longer like 6-8hr+ my personal preference is to NOT roll hard with Hickory, it makes things start to taste to much like bacon for me. So with a 8-10 hour bacon smoke I like to roll 70% Apple and 30% Hickory. You will figure out your preferences on longer smokes as you get more smokes under your belt :)
I am 100% in agreement that chicken is the way to practice and learn, it is cheap and it makes some damn good eating!
With your MES 30 you may find that the max 275F temp of the smoker may not give you edible chicken skin.
A cool first test for you would be to buy a small pack of chicken quarters and a split bone in chicken breast.
Remove the skin on half the split chicken breast and on half of the chicken quarters you smoke. You will see how drastically different they may turn out or how similar they may turn out.
Also this little test would allow you to brine the chicken breast and not brine the leg quarter/dark meat and see how the dark meat is naturally juicy and how the chicken breast matches the dark meat in juiciness when brined :)
With chicken you can experiment over and over and over with great results! Every time I make a modification to my smoker I basically practice with a whole chicken smoke hahaha. Doing so made me wonder why people don't smoke more chicken, it comes out soooo good.
Finally I would recommend you getting a vertical chicken rack or two. I have all of the following racks:
Double vertical chicken rack that converts into a roasting rack:
Single chicken or Turkey roasting rack, it is tall and handles turkeys well where the double wrack doesn't handle a turkey well at all in the vertical position:
Rib rack that can flip and work as a roasting rack, the jury is still out on it's feasibility as a rib rack to separate mutle racks of ribs:
I find all of the racks handy but I like the dual vertical chicken rack because chicken is so cheap and when smoking meat for some people 1 chicken is never enough :)
Oh also here is my Franken MES40 with mailbox mod and
AMNPS.
Let me know if this all makes sense and Best of luck with the first smoke! :)
