Not usually Terry. They are proving very difficult to reproduce in captivity most of the time. Only a few people have had any success at all. Jerry Fife just produced his first four hatchlings a couple of months ago. Most zoos have failed entirely. Males are hard to come by. From what I have gathered there are several different sub species from different areas with in the range and they do not inter breed well. DNA testing is helping to sort things out and get the right groups together. Everyone is hopeful for the future.
