I ordered online and hatched with some success some Dutch Bantam Eggs this past month. They arrived in September and hatched in October. Feeling confident about the seller's eggs, I ordered another ten. But for some reason they don't appear to be fertile, there are one or two that when candled appear to be developing, but otherwise zip. Its now day 20 and not even a pip. I keep hearing weak chirping, but I think it might be my imagination since I just recently hatched some eggs in the same incubator and I am sensitive to every little squeak I hear coming from that direction. Are eggs that are laid in Fall less likely to be fertile than eggs laid in the Summer? They must be mating more when the weather is warmer, so it makes sense that the fertility rate goes down with the temperature. The eggs come from Chicago (west) so I am pretty sure they are experiencing significantly colder weather than we are in Southwestern Washington State, even though it is wetter here. I'm thinking that it is best for me to stay away from the online auctions until the Spring. It will be hard, since it seems quite addicting.
