I've done all 3 ways, point of lay, chicks and hatched eggs. To be honest I've enjoyed raising them all 3 ways.
My first ones were P-O-L, that was easy, no other birds to contend with as they were my first, they all came from the same flock, so already knew each other and where they sat in the pecking order, and they just got on with it. A couple of weeks later they were laying eggs for me. They were friendly, never been skittish and all knew me pretty quickly as chief food bringer so always came running when I went out.
One of those went broody, so I allowed her to sit on some fertile eggs, she only hatched one (which of course was a roo!) and she raised him in the flock. He was picked on a fair bit by the others while he was little, but pretty much just pecking order thing, but boy did he get his own back!! Once he had matured he had his wicked way with them to the point that they were bald! Poor things. Although he was never aggressive with me and was actually quite sweet with me. Unfortunately we decided he was too much for my ladies and he had to go. I was pretty sad, but that's what happens to the boys in chicken farming!

And peace was restored to my coop.
Next lot were 3 week old female chicks, slightly harder to deal with as there was no broody to look out for them so had to be kept seperate. Every time I tried to integrate them they were hen pecked! They were quite skittish and scared of everything including me. So it was a case of trial and error, but eventually managed to merge the 2 flocks, they still get bullied a bit by the original girls even now, but not all the time, so they're okay! And they eventually got used to me and then also came running when I went out there.
Latest addition, one of those went broody, so I allowed her to sit on some fertile eggs. That was stressful, we had a few issues along the way and this broody only managed to hatch 1 so we bought her some day old chicks. Snuck them under her and away she went. It's wonderful watching her raising them, They really are so cute, but they are only 3 weeks old, so we're yet to find out if they are male or female. Hoping we get one roo, as I'd like the chance to hatch some of my own hybrids next time we have a broody.
Each way has its own merits, I think hatching is probably the most stressful and the least guaranteed, may get a poor hatch rate and they could be all males! Buying chicks is slightly more guaranteed, but again, can't always tell if they are male or female in some breeds, and some chicks don't make it either. Point of lay pullets are probably the easiest and most guaranteed as a start point and you start getting those all important eggs almost straight away.
Sorry, longer post than I thought it was gong to be! Anyway, best of luck with your flock, however you decide to go about it.
