congrates! pituophis, especially northerns have a very strong nesting instinct. jim Kane taught me about nest box strategy and I have used his techniques successfully for many years. That is not to say that these are the only good techniques or the best but they do work. I use rubber maid or tupperware bowls with a hole cut into the top. Match the bowl size with the snake size. They are clear but that does not seem to matter. I generally stuff the bowl with green moss which can be purchased at hobby stores. I do not use spanish moss or fake moss. Wet the moss thoroughly but squeeze out as much water as you can. I generally pick out any twigs to avoid poking an egg but have never had any problems. I generaly use a few strips of duct tape to hold the lid on as bigger snakes will pop it off in the process of nesting. They seem to really get into "digging" in the nest boxes and will move out some of the damp moss material.
Kane's rule of thumb was "make it a really tight fit", which I presume makes the female feel more comfortable about the space being a good place to deposit her eggs. Even my absolute longest, largest female will lay in these 5.2-5.3 liter bowls. This astounded me initially but when you consider how small of a space that a 6 or 7 foot northern can hide in it makes more sense.
I really worry if they go much over 10 days from the pre -laying shed. retained eggs are a serious health problem for the female. Much later than 10 days and the eggs are generally no good any way. There are exceptions as noted in a previous post but it has been my experience that 10-13 days is about the limit. If this happens get your animal to a GOOD herp vet.
I tend to check daily on expectant females without disturbing them. Once they start to lay I leave them for 24 hours at which point I remove the eggs but leave the nest box just in case. Then start to feed with fequent smaller meals as reproduction is very metobolicly costly.
I generally pick off any of the moss when I set the eggs up in vermiculite to avoid contamination during incubation.
I LOVE THIS TIME OF YEAR! Sit back and wait for those tiny little snake heads to come pipping out of the egg!
