@BReeder!
x2 on waiting for the fan before adding eggs. The change in air flow will cause a change in temp / humidity. It's best to have it set up 100% so you don't have to scramble after the fact. (Some wild swings could occur during set up) Also make sure to set the eggs on a day you'll be around to monitor & adjust settings as needed. I put my fan blowing upward. I also added a tiny scrap of screen across the bottom to prevent accidental decapitation. (Never had an issue but better to be safe.) I've seen people aim the fan down but then suspended a piece of metal or cardboard to deflect the air currents to the side.
My lav orps & Spc sussex have a pinkish hue to their eggs. You'll probably be able to identify a new layer by her comb color. They change from pink to red. (Also can check the vent.)
No bunnies here yet. During this cold weather, I'm enjoying those empty cages - not having to clean or feed anything extra! The chickens are still locked up in the coop - and thankfully, no pecking - so the winter number must be OK. (i even have those 2 temporary turkeys in there!)
Speaking of pets: Eight years ago DH got a doz feeder fish as a gag gift, and the running joke was that they'll only live a few days to a month. As expected 11 died within 3 weeks, but the last one lived 4 years!!! We simply named it "fish" because it was only a temp pet. DS kept talking about how he remembered "Fish" and wanted to have a pet fish again. Santa gave him a robotic fish last Christmas, but it didn't satisfy his fish desire. So, Grandpa gave DS a fish tank. Once it's set up, DS will get to go & pick out a couple fish. I've only had goldfish, so does anyone have a suggestion for an easy care beginner fish? It's a small 3 gal tank, so preferable something cool that won't grow & need a bigger tank.
