Incubating method's-calling on the pro's

It looks like you are on the right track. I agree - be thorough with your cleaning. Oxine can also be used for fumigation. I also do a tylan dip of all eggs prior to incubation in order to reduce disease and myco in my flock.

I also incubate bantam vs. standard eggs differently, using dry incubation for first 18 days in my bantams and 45-50% humidity for standards. If I have to incubate both types together then I lean towards lower or dry humidity range. I use multiple thermometers at different levels - even with fans you will get pockets of temperature differences. If you can rotate/turn your egg trays to different positions to minimize effects from air pockets.

Also, avoid opening up the hatcher as much as possible - leave the fuzzies in there until you absolutely need to empty them out (they are good with their egg sac for food for a long time!) or you will affect the other eggs pipping and the chicks working their way out will not be able to pip correctly.

And yes, switch to a breeding diet a month prior to collecting eggs for hatching.
