I don't know Ralph personally and don't always agree with everything he writes but have seen enough over the years to have no doubt that he cares for animals. Among people concerned for animal welfare legitimate differences of opinions can be had concerning if it's best for the morph or even the individual animal to put down defects.

Many things are genetic but I wouldn't automatically assume a genetic cause for every defect. If it's not genetic and separate from the desired mutation then culling for the sake of the morph goes out the window and the next most important question is regarding the animal's quality of life.

From the pure money standpoint the best thing to do would have been to put the deformities down and never mention them to help keep the public ignorant of any potential issue. By posting info about the issue he opens up questions about whichever morph in general and his animals in particular. In the long run I think discussing deformities in public will help us find the solution to reduce the numbers of defects. I believe sharing this information is even more evidence of concern for the animals over concern for money.
