Hello everyone! I am joining your hatch-a-long. I won my first incubator ever and it's coming on Wednesday. It's a brinsea mini advance II. Seems pretty straightforward... is there anything particular I should know about it? I'm super nervous to try hatching eggs in an incubator- I've always given them to the broodies! I won 8 eggs along with it that will be a mix of some colorful egg layers it sounds like. I am picking them up - so not shipped. Yay! I said I was done for the year with hatches, but if you win a contest, you win a contest!

The eggs are actually from Highland Homestead

I might have many questions to ask you experts here!
Should I leave the incubator to sit for awhile before I start it up? Would you recommend buying a hygrometer with this incubator and which kind? The incubator holds 7 eggs it says, but I'm getting 8. Can I stick the extra one in there somewhere?
I'm excited to see all your hatches! I'll attach some pictures of my "last" chicks I bought a few days ago. Supposedly a Rhode Island Blue, Sapphire Gem Splash, and a Barred Rock. Never heard of the first two before.
