>>My vet said
>>expect her to be off food for at least a month.
Don't bet on this quite yet. Continue offering food to her throughout the entire gestation period. I've never seen a female go off food for a month before laying... Maybe a week or so, but a month seems a little extreme.
>>The vet did give me oral calcium to give
>>her every 3 days.
This may or may not help... But it certainly wont make the situation worse. It may be too far into the gestation to start adding extra calcium and still see benefits. You will want to continue the calcium supplements for a month or two AFTER she lays eggs too.
>>She also instructed me to use topsoil
>>soil for her to lay them in.
I use a 50/50 topsoil & sand mixture. It holds water better, and will let her dig a burrow that will hold it's shape. Get the largest rubbermaid tub you can find, and cut a hole in the side or top of it just big enough for her to climb in. Fill it 2/3 full of the dirt/sand mixture. You should try to have at least 1-2 ft of dirt for her to dig in. You may have to show her the box a few times so she knows what it is...
>>Please give me some tips
>>on what to do and how to ensure she gets enough water.
Bathe her every other day or daily, for starters... Will she drink from a spray bottle? This is usually the easiest way to get an ig to drink for you. Also mist her food heavily with water every day, to make sure she gets enough moisture from her greens.
It will be most important to watch her for egg binding, be very careful with handling (don't break any eggs while they are inside her), and keep her comfortable so she can lay her eggs in peace.
>>this the usual time of year for eggs for them? Does the
>>end of June sound accurate?
I've seen females lay eggs at all different times of year, although late spring/early summer seems to be most common.
The iguanas I have seen die during egg laying were usually not in optimum health, and their other problems make the egg laying more difficult. A healthy female with a proper egg laying site will usually not have problems. On the other hand, I had a female lay eggs from a shelf 6 ft off the floor of the room once, and she continued to walk around the room for several days, laying eggs wherever she felt like it. This was an odd case though...
Good luck!
