I have 300 quail eggs incubating,100 set over a 3 week period. The first 100 was taken out of turner on day 14, the eggs started hatching on day 15,20 hatched by day 16 but 6-10 have bad legs and can not stand. I held the eggs 6 days indoors at or near 70 degs before setting them. My incubator is a sportsman 1502 . Readings for temp is a constant 100, humidity was between 50 and 55 until day 14 when I added the wick pad which raised it up to 65%. Eggs were not candled but my breeders are in breeding pens with 1 to 4 ratio so I figured most are fertile. Has anyone run into this problem before? What is the fix?
