Well, haven't been on this site for some time..... this theory did not prove too work so well. Out of 11 eggs, i ended up with 6 hens, the rest roosters. I'll try again this year if I can get an incubator.I plan to keep some eggs from my layers to hatch . I have a buff orfington roo and a mix of other hens. mostly RI reds and a few Wyandottes. So I want to pas this tidbit on- someone told me that if you keep the eggs that are more rounded than pointy, you will have more hens than roosters. this person told me that it is an old theory and that they have used it with pretty true results. So- I am going to try it out. I'll be starting incubation in the next few weeks, so I'll post as thing progress.
Has anyone else ever heard of this?
