Thought I'd share a generic version of what we use for keeping track of our hatches. This was built on a spreadsheet. We are currently running two breeding pens. Its easy to use.
For the first set of the year, note the date the eggs were set, and when they are due. Record the number of eggs set, and how many from each breeding pen as applicable. after the first candling, note the number of eggs that did not start and the number that are viable, or developing. aFter the hatch, record the number that died in the shell, the number that hatched from each pen, the total that hatched and then the number of pullets and cockerels from each hatch. I know that much of this doesn't matter to many, but by using this chart we can know how fertile each pen is, what ratios of pullets : cockerels we are getting, the overall fertility and hatch rates of each set. With this info you can adjust the incubator temps or humidity if needed and keep track of the results. You can also know at a glance which roosters and hens are making the most babies...
