If you're getting them young from a feed store or the likes, you will have a chance to grow with them. It's really not so hard.. They DO grow quickly mind you..
As OrpingtonManor said, playing with the cute little fluff balls that are chicks is really enjoyable, beyond being pooped on from time to time, but heck, my kids had done about the same at least once in their life.. Must say, theirs was much less enjoyable... not saying that I enjoy it though..
Chickens are like many animals and really like to feel secure when lifted, so lifting them under their chest is the best. Mine are still small enough to where I pick them up just by grabbing them with one hand over the back.. They don't enjoy it, mind you, but where they're at now space is tight.
Mine are sitting right beside me in a dog crate.. Have been since we'd got them, in fact.. They're extremely friendly now as I work from home and are beside them for at least 10 hours a day. Of all that I have however the Barred Rocks and Sex-Links are the friendliest of the lot. The Barreds always love to be held and are the first to the door if they think I'm going to pay attention to them.. Which they often think I am.. Silly things.
Chickens, are not like birds of pray mind you.. So you don't have to worry about any talons sinking into anything. They play a balancing act when perching and only use their talons for scratching in the dirt. You might get poked now and then, but nothing bad at all.
Now, as far as pecking.. I'd found that [older, 4+ week old] chickens are much like crows in that they're "oooohhhh! shiny!" obsessive and will peck at shiny metal or my daughter nail polish so if you have an aversion to that to start out with just take off your wedding ring and any ear rings you might have in. It's really not painful though..
One of their favorite treats right now is Rice Krispies.. I take some and crunch it up a bit in my hand and let them eat it out open palm. It's funny to watch them.. A group of 10 gets a tad overly excited about it all, but just a pair would be fun for you to feed like that. They might nip just a little, but it won't leave any marks..
It's really been quite fun.. Right now I've got two parakeets and a cockatiel and I must admit, the chickens are by far the most personable, friendly and fun birds of anything I'd ever owned.
