It's hard to say with any amount of certainty, because there are so many variables. The fancy birds will pull a higher price tag in the urban setting, but only if they're female. That's a lot of unsold males. The rural setting leans more on production, and the well known layer types that are consistent and reliable are going to do better in terms of quantity.
Good breeding stock always pulls money, depending on quality and the reputation of the person selling them. You can't get that reputation over night. If you spend enough time learning about breeding, you find out where to get the best stock from, and it isn't a pop-up breeder on
Ebay.
I've always had fancy or obscure poultry, just drawn to different types. Right now we're in the experimental phases of breed selection, to pick which ones we're going to stick with. To us, merit matters. Health, vitality, laying ability, and table size. Often the rarer breeds have issues to over come in terms of health and productivity, from interbreeding. You can't just buy them, raise them, and then expect the whole group to make you tons of cash 6 months later. That's a suckers bet.
You have to carefully select your breeding stock, consider their points of merit, keep track of who's related to who, build it up through other sources to increase your genetic pool. Hatch lot's and eat the culls. If you sell all the culls, this puts a lot of subpar birds out there for people thinking they can make money off of them, and the flaws within that breed will become more common, and the price will drop accordingly. Except from those producing the good ones out of a solid breeding program.
If you're going to make any money, it's because you did it correctly and got into it for the long haul, and staked a reputation on it.
Buyers want to see clean, healthy, nice looking birds. This means you need the space and the routine to keep them that away. I can't tell you how many times people have come to pick up birds and they comment on what a relief it was to buy from us and they wanted to know the next time we had birds available. They told me horror stories of other places they had bought from, where it felt more like a rescue than a purchase.
You'll know you're doing it right if you have a waiting list and repeat business. Compliments instead of complaints.
