I have a riser! I use it on my "hatcher" (an older nr360 that can't be reset to turn any more) and it gives my babies so much more head room! It's also been great for when I get shipped eggs and need to incubate upright for a few days (although there's a 3d printed piece for that too).
Well, my two best Silkie hens from my blue/splash pen went broody, so I gave in and gave them three eggs each today, due to hatch 3.01. I'm also going to be setting an undetermined number on Friday from my Cuckoo, Blue Cream, and Splash show pullet cages for a 3.03 hatch, if any of them are...
