Shipping is the riskiest part of a baby chick's life, or so it appears. If they make it to you in fine health after being subjected to the uncaring treatment of USPS, then you are probably getting pretty good chicks from established and reputable hatcheries. First time I ever ordered peeps online dilivered by mail, I received my order 8 days ago and got 17 out of 17 cheepers in perfect condition. BUT, my post office is in a very small town, a few hundred residents, one girl working the post office by herself and she always remembers me. Have them shipped to a major metropolitan area post office and you won't get the same customized/personal service. Long transit times can subject the babies to rough handling and dangerously high or low temperatures for a full day or two, easily. The first week or two of a chick's life is very temperature critical. After that, you have a bit more wiggle room and after 3 or 4 weeks for most breeds it is not the big deal that many people make it out to be. The thing is, the shipping is the most dangerous part of their little lives, and with day-old peeps that is also exactly when they are most vulnerable.
So, depending on your location, locally bought poultry, even at a premium price, might be the way to go, especially if you only want a handful of peepers. If you intend to never eat them, then you probably will want to sort of bond with them like pets, so picking them out in person can be a real event. THAT ONE, the one with the funny little waggly walk, and THAT one, the one that likes to jump! THIS one, she came right up to my hand to check me out! Sort of like adopting a new dog from the shelter or buying a pup at the pet shop.
Sexing them is an art and you can be wrong even after watching every single youtube posted in the last 10 years. But the feed & seed can be wrong, and the hatchery can be wrong, Old McDonald and Mr. GreenJeans can be wrong, too. And if you just want two or three, raised pullets honestly are not THAT expensive, and you don't have to worry about caponizing or harvesting or re-homing a noisy rooster if your neighbors make a stink.
I will say that capons can be very friendly and live a long time, even if you don't want them for roasting. Hard to find a vet that will do it, though, and DIY is risky, for that first attempt, so not a great idea if you won't be operating on chicks on-going. No DIY surgeon wants to be 0 for 1. 9 for 10 or 99 for 100 is a bit easier to live with. First attempts can of course be successful and usually they are, but the risk is there, because there is no teacher like experience, and you don't have any of that yet.
There are anti-crow neck bands, too, but if not applied properly they are uncomfortable or even hazardous to your rooster, or else the rooster can still crow loud enough to set off car alarms.
Re-homing the boys can be difficult in a city or a densely populated suburb. For the same reasons you don't want them, your neighbors won't want them, either. Some breeds can be released into the wild and do fairly well, some breeds definitely not. In New Orleans, where we used to live, backyard chickens are a thing, and especially since Katrina, there are several flocks of feral chickens right there in town, roosting in the oaks, scratching and foraging on vacant lots. But roosters released into the wild probably not live long and happy lives without human care. If they are young, it may simply be more humane to harvest them as fryers, however you might feel about it.
Buying raised pullets ready or nearly ready to lay, is a nearly foolproof way to get laying hens without any roosters. If you are buying a dozen, then the economics of grown or nearly grown pullets don't make much sense, and you probably want babies, even if that maybe gives you unwanted roosters.
With a tiny mini-coop, you might consider getting a second one, and then go ahead and get 4 or maybe 6 sexed pullet chicks. That will pretty nearly keep a couple or a small family in eggs or nearly in eggs, when the hens hit their stride. With that small a number, you can give each one plenty of bonding and personal attention if you are into that, or if you have kids.
