Mine came from Premier 1. Good stuff, but not chick proof. They squirt right through it. It still needs extra TLC re: ground contours with added posts and staples. I have the double peg kind. I think they sell some netting stuff to put inside it to keep chicks from going through. Save yourself some money, and buy some deer fencing. It comes in a 7' roll. You can cut it with scissors to what ever height you need, then use fiberglass poles to hold it in place. I surround my garden with it. Keeps chickens out, but cat has figured it out.
I'd not worry about wry neck until after he's 3 - 4 days old. It should self correct, unless he's also displaying neuro problems: star gazing, moon walking, spinning...
Congrats to all of you who have recently hatched, or are in process.
They're probably still working on yolk reserves. They'll come around when they are ready.
SW: I bought the same thermostat, and plan to use it for my next bator build.
