My girls went from just wanting to do Chicken 4H books this year to also doing egg and chick for the 8 yr old and Embryology for the 15 yr old. We tried to make our own candler and it didn't turn out well, so we've been using the brightest flash light app for my android phone. It's working good but I'd like something better for our next set of eggs when they will start their project books. So I was looking for opinions about the best egg candler? THANKS in advance to everyone who replies be sure I'll be sitting here reading. My girls and I are learning so much from this site and others that we've been reading nonstop lately. Just by seeing what others are doing we get a good idea of what we can try for our own small but growing flock of chickens.
