I know some people would probably rather not know, but I am someone who does not like surprises. Thus, I'm going to lay out some of the costs we've had with exhibition poultry via very small time 4H.
Chicks: breeder quality chicks seem to run about $7-10 apiece delivered. We got 5, which was enough so that we could pick the best ones from our group, and enough to ensure that we'd get some of each gender, and enough that one or two losses were not catastrophic. Note that "delivered" comment - even if the chicks are less, shipping on a box of 25 will add about $1.50 per chick.
Brooder: We bought a $30 rabbit cage and a $5 heat lamp, and used a thermometer we already had.
Shavings/bedding: incidental - I stole a small amount from our horses. You could probably cover yourself for a year with one or two $7 bags.
Food: I haven't kept close track, maybe $100 a year
Coop: we had one already, but if you build one, it's easy to spend $200 or more to make it secure unless you're flush with materials. Better do it right the first time rather than face the dead chicken two days before the fair or the day after Christmas... and then spend the $200 anyway.
To go to the fair:
- You'll need a white long sleeved shirt and white pants, and you know you won't use 'em for anything else.
- 4H hat and tie/scarf, about $10.
- Entries are cheap, but the adult has to pay admission, runs $10-$16 per adult.
- You'll need a carrier - we used or brooder cage, or you can use a dog carrier. A cardboard box can do in a pinch, but you'll be wanting something better. Make sure it has plenty of airflow so that you won't be overheating birds in the summer.
- At our most local fair, the chickens have to arrive Tuesday evening and cannot leave until Sunday. This means daily trips to the fair to care for the chickens and participate in various events, or camping at the fair, either of which have costs. Other fairs we've attended have shorter stays; one is a single day event. One of the fairs is during the school calendar; we coordinate with another family so my daughter doesn't miss school just to feed her chickens. The gas adds up if you're going every day, or worse, twice a day, plus your time.
- Food and water containers for the fair, can be as simple as disposable cups with clothespins. Other people have waterers that snap on to the cage. I gave my daughter the reject ceramic bowls I made while learning to throw pottery.
- You'll probably make up some sort of laminated sign to tell the public about your animals.
- There's tiny prize money, but it made me laugh when she got a check for $1 her first year, which didn't even cover a cotton candy.
- Fun fact: if you were going to the fair anyway, the entrant usually gets free admission. So that can be a savings... and maybe if you do an art or craft that is covered by the fair, entering may be cheaper than the parent wristband.
If money is tight, there are sometimes people willing to sponsor or to do hand-me-downs for things like cages. There may be someone in the community with extra chicks, or especially, an extra rooster. Try craigslist, too.
