That is an odd state law but there is safety and warmth in numbers so it might not be as dumb as it sounds. Did you look on CL? Chicks are big right now around me plus all the feed stores are selling out of them as quick as they come in. Most hatcheries sell a minimum of 25 chicks (min of 5 per breed) so they stay warm in transport. Maybe try that next year and get orders from friends or sell them on CL and pay for your chicks (that's what I do). It's no more work to brood 25 than 6 for the first 2 weeks.
Golden laced Wyandottes are my all time favorite. The first time I say one, I was hooked. I had to have chickens.
