Sorry. GL!!!Thanks. I do not have a problem with temperature fluctuations, but only with the humidity. I think that the early drop to 26 degrees one night stopped the developement of all but possibly 4 eggs. There was nothing when I candeled them at about 10 days or so.
The four that seemed possible to hatch did ndot, but I did not think they would. I was going to crack the eggs before thowing away, but was not up to it.
I will keep trying. I would like to replenish my flock of Salmon Faverolles. But it may be a good idea to buy some from a different hatchery for different genes.
