Im on day 8, just about 9. I got the 60 eggs from a lisenced CA gamebird breeder, he practiced strict bio security, and washed/sanitized the eggs. The eggs were also refrigerated for about 2 weeks prior to me getting them. I let them sit out a full 24 hrs before incubating. I just candled 26 of them, from spots all over the cabinet incubator I built specifically for them. Every single candled egg I looked at was going full bore! Great veins, and very active embryos. I can only assume I will surpass the breeders estimate of 85% hatch rate, I also got a dozen jumbo pheasant eggs, and the ones I can see are going strong too. These eggs were also sanitized and refrigerated, tho I think only for a few days. They say chukar eggs stay good for at least 3 weeks, and the guy told me he been gettin better hatches the longer he waits. I guess I am just amazed at how fertile these chukar eggs are, I mean they been thru alot. I am liking the sanitization and refrigeration factors here. This really makes me believe that eggs arent as fragile as we make them out to be.
