My last hatch of cuckoo marans, the largest eggs yielded chickosaurs. I have quite a few large ones in this batch, so I think I could test this theory better than the highering of the pointiest eggsI found that with my last incubation, the large eggs did not fare well. Very disappointing, b/c some of my gals only lay very large eggs. I'm not so sure if it was strictly related to egg size, or may have been related to the fact that all of the large eggs were on one side of the bator, and the temp may have been off on that side.
