Do you mean another job that pays $500 a week and then the birds as a sidejob?
I'm contemplating doing the same right now and am looking at about a $15,000 investment to expand my pens, buy eggs, equipment, marketing, licensing, plus the major expense of feed prior to being able to sell any birds at maturity. That isn't quite the total expense but I hope to have sales to have the money to finish the remainder of the birds. I am looking at raising about 2000 pheasant and 1500 chukar.
I have not decided, yet, if I am going to go through with the expansion, but I have run all the numbers I can think of to make sure I know what it will cost to do this. I raised about 250 pheasant and 300 chukar this year and the pheasant reach maturity in a week. I plan on going to a handful of game farms and giving them a few birds to take out themselves along with a brochure with my price list. You can sell your birds as cheap as you want but if they aren't good flight birds, nobody will buy. Game farms need top quality birds or they lose their customers, trainers need top flight birds or they can't train. I've already sold a bunch of chukar and they did well and am waiting to see how customers like my pheasant. If I can't guarantee sales, no expansion. The first thing I suggest if you plan on going "big" is making sure you have customers that are willing to buy. Otherwise, buy a big freezer
