I don't do anything with mine. However, I set about 300-600 eggs weekly. When I first started incubating and was doing 20-40 eggs a week I would candle and look for shadows or clear around day 7-8, but now I don't do anything just put them in, put them into the hatcher and see what happens!How do you all monitor your egg progression? does anyone candle these small eggs? or weigh them? or is it more of a set your temps and cross your fingers?
