For those that have hatched enough eggs to begin having usable stats, let's say 50+. What has been your rate of non-viable deformation in eggs that have gone full term? These numbers should not include incubator accidents or known genetically risky breedings (spider x spider) etc.
My numbers are sitting at 1 in 70 where the animal needs to be euthanized on hatching. My rate is the same at this point whether it is a closely related breeding or a totally unrelated one. Typical deformations seem to be severe kinking or underdeveloped lower jaw. In every case I have had so far, the deformation has not been repeated with the same breeding and it has always been a single normal looking egg of a larger clutch (8 or more).
My latest problem was this weekend, very nice clutch of 9 large eggs with another "world's first" inside. Mother and father are solid breeders and the pairing has been done before. Eggs piped Friday, right on schedule. I cut and everything seemed normal. 8 of the 9 had heads hanging out within a couple hours. The next day 4 were out of the egg but one still had not come up for air. As is normal for me, I prodded the rest of them out of the egg. I had to remove #9. It was alive but so severely kinked it could not unwrap itself. I chased my kids of the room before they noticed and did what needed to be done.
Any data anyone else has gathered would be helpful.
Thanks
