They don't eat too much the first couple days, but make sure their dishes are full beyond that with chick food, or medicated chick food. One thing to be really careful of, is that their water dish isn't so deep that they could fall in and drown. I pack my water dishes with marbles the first couple weeks, as chicks are kind of uncoordinated. I've had the unfortunate experience of drowning happening before, so I'm extra cautious. When you have a lot of chicks, they like to huddle in one giant chick pile, but with just a couple, you may find that a clean, new feather duster put in the brooder will help them feel at ease. Just check them often. I had a baby bantam chick get stuck to the feather duster just this morning by her own poo that had hardened under the heat lamp. She was fine after I cut her loose, and washed off her foot. Honestly, I never expected that, so just look for anything out of the ordinary. Check bums for pasty butt often. Clean as needed. I recommend a thermometer in the brooder for that few of chicks. 95-100 degrees the first week, dropping 5 degrees each week there after, In larger groups its easier to tell if they tend to be too warm or too cold without a thermometer, but with just two, you need to watch them closely.
They will find the food on their own, and water too, but if you're worried, you can dip your fingertip in water, and touch the end of their beaks with it, to get them drinking. Be careful not to get it in their nostrils.
I keep paper towels in the bottom of the brooder the first week, then let them have shavings during week two......
That's all I can think of !!
Congrats on your babies!
