I sold some of my fertile eggs to a friend and she just posted to her facebook that they're pipping and chirping! I'm excited to see what the chicks look like, I haven't hatched any of my own eggs before and this is the first batch of fertile eggs I've sold. I think we're both kinda surprised that they're hatching, she said she had her incubator temp. spike up to 102 several times for about a day each time. I can't wait to get an incubator and hatch some chicks of my own!
