It's a matter of how they were raised, whether the owner made good efforts to socialize them. If they did not with started pullets, then they will probably not be friendly, or at least most won't. It's partly dependent on the individual's personality.
Glad you could join the flock! I agree with Judy that it all depends how they were originally raised and their personalities. It is possible to tame older birds with a little time and patients. Food is always the way to their hearts. Food and sitting out with them and chatting to them really gets them used to you being around. I have tamed older birds this way and it makes life so much easier if they need to be checked over. On the other hand chicks are so much fun to raise, they really do tame well. It's very rewarding raising chicks.

Generally, it's safer to get chicks since you can tame them yourself. There is no guarantee that the pullets will be friendly and at this age, it is hard to tame them. So I'd say go with chicks. Plus they are fluffy and super fun to cuddle with. Here is a link on taming them right from the start https://www.backyardchickens.com/a/how-to-tame-chickens-from-the-start
Awesome, and thank you so much for the warm welcome!!! We originally bought 4 started pullets, and had a lovely working flock going, until the neighbor's dog noticed we now have chickens and broke through his shock collar and killed 3 of my 4 precious birds. That was about 3 weeks ago and I still cry over it!!! Chickens take hold of your heart quick!!!
So we bought another started pullet to keep Barbara company, while we raise 5 chicks up and can blend the flock. The chicks are awesome and not as much trouble as I thought they'd be. They tamed fast and are so wonderful and friendly. I was just curious if that was going to wane as they grow to be the age of the other two, or because we are their people they will be more affectionate.
Thank you so much for your replies and being such an awesome group to be a part of!!
