Still hand turn all my eggs. Tried egg carton with tipping last year detested it, but that's me. Am lazy but more restrained budget makes me keep to the cheap side. Profit this year actually is in the black but still won't go bananas besides hatching a few hundred chicks...... do I have enough yet???? Wife even made offer buy me another bator if I "needed" it. A cheapo styro but have had luck for 8 years with them.
I have 2 shelves that are stacked. Made from 1x3 wood and welded hardwire that hold the eggs well enough. No issue with circulation or heating. Each shelf hold 60+ chicken eggs. Could add another if I wanted since the top is 6 inches from top of 1st shelf. But as it is I have "adequate" hatch space. Filled to the brim I could cook over 200 eggs (counting what the 2 LG's hold, but hatching in these for now) if I wanted. But until I get brooder room ready I am not gonna set a weeks worth of eggs (20 dz. table eggs a week that run with BSL roosters, and whatever the breeding pens lay). When pure roosters mature and I sort down table egg flock I might get to close to that. But now I am content with what I am hatching.
Come fall, when roosters are mature I will have RIR,BO,BPR,WLH,BA pure breeds. And a lot of BSL. This isn't counting meat birds (My own CX X) or ducks (Rouen, back up to 8 from 1, and more hoping to hatch.). Wife kids and family friends are all on my side this year (Not always the case in past.) even neighbors are donating used poultry equipment for the birds. Honestly it comes down to 1 simple fact. EVERYONE wants my eggs. SO nice to be loved (Even if its only for my eggs/birds LOL). And I have open invite to a farm store as an outlet for eggs, but as it is I have more orders than eggs so far. I need a 5 month FF button please.
