When younger, my sister did very well with the string and needle test for guessing the sexes of children of women she would meet. Predicting the sex and number of children that were to come in the future was not very good.I was browsing YouTube and watched a video of a gal doing the string and needle old wives tale to guess the gender of eggs. She admitted that it was a tale, but she was certainly hopeful it would work. I think I’ll try it with my next batch of cream legbars, since they are auto sexing at hatch. Just to prove it impossible. Lol
You could always get an auto sexing breed and cull/sell/give away roosters before they crow.![]()
