Sorry to possibly be a downer here, but it's the zoning, town, and/or home owners association rules that matter, not whether the nearby stores sell chicks. Some places also allow hens but forbid roosters. Odds are if your property is large and you can't hear or see your neighbors easily, or if your property is surrounded by farms, then you're most likely in an area where it's completely fine. However, if you're in a suburban area with more closely packed houses, or if there's a suburban area to one side and farms to the other, there may be no-rooster rules or even no-poultry rules. Unless you are on a farm or in the middle of farms, you will want to verify your local laws right now. In the event chickens aren't allowed, it will be much less painful to give the chick away now than to be forced to give it up down the line if some unsympathetic person reports it (happens to people all the time unfortunately - there are many threads on this site related to it in the laws & ordinances section). As a point of comparison, I'm in an agricultural area where all poultry is fine, but 10min down the road it's a no-rooster area due to being a more closely packed town. Where exactly the rooster vs. no-rooster line is drawn really is not obvious just from looking at plots and houses along the road. The people from that town and I shop at the same farm supply stores but the rules for what we can keep are different.
You also didn't list whether your chick was sold as a pullet or what breed it is. If it was listed as straight run, there's a roughly 50% chance you could have a cockerel, which is more likely to be a problem with any close-by neighbors (and possibly a problem with dad if he likes things quiet). Even if your chick was listed as a pullet, if it's not a sex-linked breed where then the determination isn't 100% accurate and there would be a very small chance of an accidental rooster that starts crowing at some point.
