I have 4 incubators....Do you have two incubators?
Just thinking it would be easier if your going to have offset hatch days to have a lock down incubator.
I personally am adding in my chicken eggs on the 11th so I have the same hatching date.
Goodluck!
Since they are your own eggs there shouldn't be any problem with holding them for up to 2 weeks before setting. Some people even hold them longer than that with no problems.
I reckon I'll just wait and set them the 11th then. I should have quite a few eggies saved up by then.Personally, I would wait until the 11th. Then they will all have the same hatch date. The oldest would be 12 days on the 11th, I don't consider eggs bad until 14 days. The 12 day old eggs may have slightly decreased hatchability, but it shouldn't be noticeable. Good Luck with what ever you decide!
