Jeff,
Of the 9 slugs I checked out none had any signs of small fetuses. She had access to temps. between 92 and 70 and she moved around between 92 and 83 (same as she did when she produced three years ago). I do wonder about the presence of the males (now I think one of my holdback females is really a male) causing the females to produce eggs. I really have little idea about how the infertile ova develop; what initiates the process, why the snakes continues to nurture them when not viable. I assume that given the right conditions the female will ovulate without the presence of a male and I thought that the ova developed only after breeding attempts (slugs develop when male shooting blanks). Now that I've experienced this I want to understand it better. I'll be Googling.
I did'nt bother her after her ordeal but I'll check and see if I can feel any left over ova (she dropped the last two well after I thought she was done).
Thanks,
Paul
...Sorry about the slugs. Was there any sign of small fetuses in them? I always look closely at them. There is more to be learned from our failures than our successes. When I have a big pile of them to look at I am always trying to figure out what I did wrong that caused them. Too cold, too hot, too something? No breeding observed? Perhaps just the presence and smell of males or their pre-courtship activities cause the females to produce "eggs"? I have had a whole bunch of slugs here over the years. 3 hours to deliver them is interesting. When I have a litter of all live babies they often get delivered in 15 to 30 minutes. When there are slugs in the litter it always takes longer. Sometimes many hours. Females that lay all live babies usually have no problems after delivery. Females that lay slugs sometimes have one or more slugs stuck in the oviducts and the results are not good if they do not get them delivered. After delivery I always hold the female in my hands and let her crawl so that I can try to feel if there are any that have not been delivered. There are probably lots of species that devour their slugs but we Rainbow breeders see it more than any other breeders that I know of. There is so much that we still have to learn about breeding these snakes.
