Hello Jamie,
Last year I crossed a Red Italian Leatherback X American Smoothie producing very close to the statistical probability of 1:2:1 (Normal:Leather/Smoothie:Silkback) that you would expect with a Incomplete Dominant Trait.

In my experience Silkbacks can be housed in the same way that I house my normal scaled dragons. They are just as healthy as any other dragons. There are some things that distinguish Silkbacks from normal scaled dragons. One of the differences is apparent when Silks began to shed, if they are not aided in shedding in the tail area the shed skin around the tail can restrict blood flow and cause the portion of tail that is not receiving blood to die. This is not always the case, but in my opinion is more common in Silks when compared to normal scaled dragons. Ecdysis constriction can be prevented but it takes a vigilant eye and requires more time to monitor the silks shedding process than a normal dragon. Another difference is that there skin is soft therefore it is of paramount importance to remove all feeders after the dragon(s) has finished eating. This is especially important with Silks as a rogue Cricket or Super Worm can chew through these guys much quicker than a normal scaled dragon. Working with silks is a steep learning curve but the reward is a new and exciting healthy morph with the ability to show more vibrant colors than its siblings.
In Regards to Kevin’s question about what would make the healthiest Silkbacks when comparing the Italian Leather X American Smoothie, American Smoothie X American Smoothie, Italian Leatherback X Italian Leatherback crosses, well responsible breeding philosophy would tell you to use the cross that will produce the healthiest offspring. To produce the healthiest offspring you want to use bloodlines that are not related or distantly related as possible. So since the American Smoothies are reasonably related to each other and the Italian Leatherbacks are reasonably related to each other you would want to use the Italian Leatherback line and cross it to the American Smoothie line. These two lines are either distantly related or not related to each other at all. Keeping that in mind I have never produced Silkbacks from line breeding Italian Leatherbacks or American Smoothies. Although I have housed American Smoothie X American Smoothie Silkbacks and spent some time observing and handling a Italian Leather X Italian Leather Silkbacks I always felt that the Italian Leather X American Smoothie had a better build, vigor, and gait. I have seen several inbred/linebred American Silkies and inbred/Linebred Italian Leatherbacks and the vast majority of them lacked quality builds, some had poor gaits, subpar vigor and a less desirable overall package when compared to the Italian Leatherback X American Smoothie that I and others have produced.
Another factor to consider is when producing Silks is the background of the Italian Leatherbacks and American Smoothies you are working with. For example if you cross a Red Italian Leatherback that came from the cross that Alessandro did to produce the first Italian Silkback and cross that to a 2006 or later American Smoothie you are most likely working with two inbred/linebred dragons. The quality of the Silkbacks from that cross are going to be less than if you crossed a Yellow Italian Leatherback, which was not inbred/linebred, and crossed it to an American Smoothie purchased 2005 or earlier, before the linebred/inbred American Smoothie dragons came out. Lastly if you cross a Red Italian Leatherback from a line/inbred cross to a Yellow Italian Leatherback that is separated by the traditionally accepted safe “5” generations you are still losing something because of the common Great Grandparents or Great Great Grandparents and the inbreeding that occurred in the F1 generation. For all these reasons it is clear that to make the healthiest Silkbacks it is best to cross the two lines that you cannot locate a common ancestor(Italian Leatherback X American Smoothie).
In closing I would like to say that Silkies are not for everyone. They require more attention, time, and skill that the average hobbyist would most likely not be able to provide. My hope is that the number of Silkies that are produced do not exceed the number of responsible, skilled, breeders that desire them.
Note: The opinions and views set forth in the above paragraphs are my personal opinions based on my experiences and other breeders that I converse with and should be understand as that.
