I never tried "Hatchright" and had to look up what it was. Please let us know how it works for you.
Before I had kids, I hatched in the classroom every spring. I once learned a valuable lesson on why clear eggs should be removed.
(I was too optimistic and left all the eggs incubating until the hatch was completed..) BOOM! I had to quickly hose off the bottom tray of the borrowed Hovabator on day 19 while a few eggs were beginning to pip. Only 4 chicks out of 15 eggs hatched. (had 8 fully developed dead embryos) 
My Valentine Hatch eggs were all duds. Several eggs were frozen, my old roo was hardly mating... and he needed some trims, and the turner wasn't properly working. I witnessed our young roo mating a few times last week, so I'll be starting a new batch of eggs on Sunday. Along with our flock's eggs, I'll be incubating a few silkie eggs for the kids. They are coming from another flock, so I'm thinking about washing them. (I read that things like Merecks can be transmitted via dander on the eggshell.) I've never washed my hatching eggs before and simply left the bloom intact. So my question is: Can anyone share how they clean/ disinfect eggs prior to incubation?
Nothing yet....my incubator may have been running on the cool side due to the extreme cold the first week. I have three eggs that seem to be quite a bit behind the others-maybe a few days? I'll hand turn those - in between work & sleep.
Happy Valentines Day!
