I have had people tell me that if the higher the heat in your bator, the chance of getting a roo increase. Is this true, and if it is, what is the temp for hens?? I have had maybe four batches of eggs (ranging from 1 to 4 eggs hatching) and I have had wayyy more roos hatch than hens. I think out of 10 babies, I have had three hens. I would love to get into raising and selling laying hens....but I need to hatch some hens first! lol Any tips? Or is my roo producing more roos than hens??
