Looks and sounds like you are doing all right, Reb.
Welcome aboard!
9-12 eggs/day from 14 hens is a good number. Be prepped for that to slow as summer comes, then a rush again and then the winter slowdon.
If you have customers willing to pay CASH - well, you might want to look into the idea of artificial winter lighting, if you havent already. Eggs are seasonal as you must know after 3 years, and it takes careful planning to keep a steady flow going all year. But you dont want to miss out on the chance for someone to give you tax-free money, so go to it!
Youre planning a late flock, so you've got the notion of flock staggering down. Thats smart!
I'm curious, though. Why Welsummers? A good laying strain, even a hybrid, might be steadier. Those darker brown Wellsummer eggs may also be a turn off to your customers.
But heck, I dunno anything. All in all, I'd say youre doing great.
