not that i specifically know of but you have alot of people on this forum that are eastern indigo/cribo experts/breeders. i'm sure they're willing to assist you in any husbandry questions. robert bruce also has an upcoming article in the sept issue of reptiles magazine. has alot of decent information in there. the only thing i would add is that drymarchon's diet should be more varied (birds, rodents, fish), supplemented, and be careful on the stock you obtain your indigos from as they have been very inbred in the states because of their threatened status and the interstate commerce acquisition permit requirement. hope this helps.
