I think it's Friday for me. The entry form said it's from the 12-16. I don't remember which day they said for judging. Just those are the days that the birds are to be in the "poultry building" which isn't indicated anywhere on the website. Best I can figure is it's the animal barns which are the southeast corner of the grounds. There's an entrance there too. So.....just in case the "oh, I gooootttttaaa haaavvvveeee" bug hits over a chicken that's for sale I'm thinking parking in the lot nearest to there.
FYI spead $40 at Fry's (excluding the usual alcohol, cigarettes, lottery, etc) & you get a free admittance for 2 adults. Just have to bring the whole receipt & give it to them at the gate/ticket booth.

And the Milk folks have a buy milk, cheese, & yogurt on 1 receipt (no size, brand, etc. indicated) & get $3 off a ticket. Couple of ways to save a few bucks.
I don't remember how much parking is, I think $10. Which I think is the same price as an adult admittance. Though there are the various things with rides, etc.
Edit: It's spend & it has to be on 1 receipt.
