I didn't quite understand the "chicken math" thing until now, as here I am setting even more eggs in the incubator.

To be fair, I bought these
after I thought some of the other eggs had been cooked!
The eggs I'm setting are Olandsk Dwarfs. I've read that they have a shorter incubation time of 19 days, like Seramas. If that's the case, I'll have another hatch on December 29th. These guys are apparently quite hard to hatch, also like seramas it seems.
I also have a batch of Dutch Bantam eggs coming some time next week, so I guess I'll be participating in a January hatch-a-long too lol
