I only deep fry turkeys anymore and will be doing two this year.
And while the grease is hot, might as well deep fry some mac&cheese to go along 
What's a good size bird to fry...and how big is your fryer?
I'm going to fry a turkey for the first time this year and don't want to recreate the wheel.
Thanks! 
I stay with the 12-14 lb size. I just have one of those 7 gallon AL pots. It's narrow and tall so it doesn't take that much oil, usually around 3.5 - 4 gallons is plenty.
If you have never done one here are some safety tips. I'm not trying to insult you common sense but these things can be dangerous. A lot of folks suffer physical and property damage every year cooking these things.
1. Outside only. No carports, covered porches, or attached wood patios allowed. Cook on the ground or driveway away from cars or anything you don't want burnt to the ground.
2. Pre-measure the oil. Put the bird and any thing else like a fry basket that's going into the oil. Fill with water to cover the bird/appliances and remove all. Mark the water level with something. A piece of tape or a sharpie or measure with a stick. This will be the maximum oil level. You don't want to over fill or the oil will splash out and flame up and your friends will start calling you "Ol' Fireball".
3. After the oil is up to temp get the bird ready and
shut off the burner. With the burner still going any hot oil that were to splash out will flame up and catch the whole pot on fire. And you too maybe.
4. Slowly add the bird. Get someone to help if necessary. I have a fry basket I use and slip a broom handle through the wire bail and get Ms. Tubercle to help. I don't like standing over 375 grease with it popping and spitting while lowering the bird. To do it safely it might take a minute or two.
5. Relight the burner.
6. Enjoy.
