Number 1:
Do not take financial advice from anonymous posters on the Internet.
Number 2:
(Since you are still reading) What is your regulatory environment? Licensing? Local Zoning? Minimum number of birds per sale? Inspections? Permits? Are you close to a State Line? Consider NPIP Participation as well.
Number 3:
Do you have assets you want to protect? If so, consider forming an LLC (additional costs, paperwork, additional tax forms, annual renewal paperwork and associated costs, etc). Will your homeowner's insurance drop you if they find out you are raising chickens as part of a home-based business. SHould you set up a business bank account (minimum balance?) and associated PayPal/ApplePay/Square etc for electronic payments so as not to comingle personal and business assets?
Number 4:
Start Up costs - build a spreadsheet. Initial stock of birds. What facilities do you need to construct? Do you need an incubator? Two? Do you need refrigeration for holding hatching eggs till you are ready to incubate?
Number 5:
Operating costs - how large a breeding flock are you maintaining? What do they cost to feed each week? Will you be replacing breeders with your own hatchlings? How long on average will they eat for free before they begin to breed? Do you have a set aside for disease/illness/injury related expenses? Have you assumed less than perfect incubation rates?
Number 6:
Market research - who are your competitors? What do they charge? What are they selling? Where are they doing it? On what basis will you compete (buying a bunch of chicks at
TSC/Rural King/Ace and letting them breed at random creates a product, yes, but not necessarily a marketable product) How will you advertise? Are they doing anything that suggests you need more research, above?
Number 7:
WHAT IS YOUR PLAN FOR EXCESS MALES?
Number 8:
Recurring costs - what are your expenses to renew your annual licensing?
Number 9:
How long can you afford to raid your entertainment budget getting this business off the ground while you grow up inventory, establish a client base, get your name out, etc?
Number 10:
Ammortize your annual renewal costs against half your expected annual sales. Add that to your operational costs. Scratch off your start up period's costs from your cash reserves - that money is lost, likely never to be recovered.
Are you breaking even? How much do you need to adjust your per bird price to break even? Is it reasonable?
and again, the first rule:
Do not take financial advice from anonymous posters on the Internet.
