I'm new at this! I bought my first chicks a year ago and I'm totally in love with my girls. I want to add to the flock and get some diversity in breeds and eggs. After asking for help in the forums - thanks everybody for your input - I've bought an incubator and I'm ready to go! BUT ...I have some more questions How can I guarantee that my chicks will be hens? When I buy eggs, can I specify hens eggs only, or is it all up to chance? I am a rural setting - roosters are NOT allowed so I have to know that I'll be getting hens out of any purchases I make. When I bought day old chicks last year I was told there was a 90% guarantee they'd be hens (and they all were). How does that happen?
