That sounds like some very useful information. I am planning to set some as well. I might do two for each day for 2 weeks and join you with some additional data points. If I don't set other eggs then I could bump up to 4 a day so that duds and such gave a better percentage. Of course there are always some duds but it would be good to see the graph of drop off. If we got a few more people we would really have a nice variety of data. Breed might also matter, so we should include as much info as possible. IF you don't mind me joining your experiment.Well I am officially 'in'. I just am not sure what I am going to set, might just be my own eggs. Might do an experiment and collect for 2 weeks, dating the eggs each day. Then keeping track of any duds and their age as I can't find any studies about how quickly age over 7 days affects hatchability.
