I wish I'd learn to save things I write because I could just cut & paste it here! That's a good question and it deserves a good answer. However, that said, one would probably have to write a book to do so. So, let me try by just saying that your question is like asking, "What's the best car?" Or "What's the best dog to get?"
I would recommend sitting down with pen & paper (or keyboard these days) and making a list of what is important to you in a chicken. Is eating eggs a priority? If so, how many per week? Remember that bantams lay much smaller eggs than LF. How about egg color? Will you be eating your "pets" at some point? Again, if you do a Google search there is a site that lists most, if not all, the various breeds in a comparison chart that can help you with some of that. There are basically four types of chickens: Egg Layers, Meat Birds, Dual Purpose, and Exhibition/Ornamental. And, just like dogs or any other animal, chicken breeds have their known personalities as well, generally speaking.
You'll also wanna give some forethought as to housing, care, maintenance, etc. How much time, effort, and expense do you plan to put into your birds. I don't have chickens as "pets" but I once watched a show on chickens and it showed one woman with a White Silkie who actually put a diaper on the bird and let it run around the house, took it with her anywhere she went, and even put it in her purse in the grocery cart while she went shopping!
But before you do all that I'd suggest doing a Google search on "Chicken Math". Those of us who understand, and have learned our lesson in "Chicken Math", all probably gave a real LOL at your "I only want 3 or 4."
