how long do they carry there unborns?
Answers:
Fence lizards (blue-belly) seem to carry their eggs(gestation period) for 3-6 weeks after mating, which usually occurs from april into mid- summer. Then they lay their eggs, 7-14 seems to be typical. The eggs are laid in moist-not wet- soil, or under rocks or logs. the incubation period( the time the eggs take to hatch), is about 6 weeks if kept at an average of 78-82 degrees f. Colder temps can add up to a coupple weeks, a little bit higher temps might speed it up alittle, but around 85 degrees or more (average), the eggs can die. Probably averages under 70-74 or so would be too cold also. You can tell if they are carrying eggs because when they get close to laying, they will be very fat, with little corn kernal sized lumps in their side.
If you have a fence lizard that appears gravid(pregnant with eggs), give her a couple different places to lay her eggs, like I described above. Medium sized plastic containers with moist( not wet) soil or vermiculite (ask for vermiculite at OSH, or other garden supply places) work well. put an entrance hole in the top of 1 side, fill them 3 or 4 inches deep with the soil or vermiculite. put it in a mildly warm part of the cage, and hopefully she will use it. When the eggs are laid, I like to tranfser them to a different container. the little plastic ziplock boxes like you would put a sandwich in work well. put an inch of vermiculite (moist, but you cant squeeze water out of it), then carefully put the eggs spaced out halfway buried. do not rotate the eggs from their original position, and if they dont want to come apart- leave them together. put them somewhere that will stay in the high 70's to low 80's, and give the container a few seconds of fresh air every couple days. lightly mist them once every week or two if needed to keep moisture level right. I f you have good eggs, and the conditions are right, the eggs should stay plump, and often get much bigger. if they wrinke, they need more moisture. It can take a couple days for them to plump back up. Too much moisture will cause mold and dead eggs. 6 weeks or so later, hopefully you will get to see them hatch.
