"They are scheduled to arrive on tuesday and i was wondering if i should separate them first or just put them right in with each other."
this depends on if they were separate before or together. If they have been apart, I would give yourself a 30 day quarintine period to make sure they are both healthy.
"Also i am housing them in a 3ftx2x2 enclosure and my day temps are in the mid 70s and low 80s(is this ok?)
How old and large are they? This is a good size and plenty of room for adults, you may want to start juveniles in somethign smaller, because they can have a hard time finding food.
"I wanted to know if it is necessary to provide a cooling period before breeding or if i can just put them in w/ each other. "
Here again, if they have been together at all recently, that is not an option as they retain sperm...Some believe that you get better results with a short cooling period, but I need to know more about how they have been kept bfore you got them etc.
"And should i provide extra calcium supplement for the female for when she lays her eggs."
I "ALWAYS" give my male and females exta calcium...it is not that expensive for a little extra health insurance.
"Also how long will it usually take for the cresteds to lay eggs"
Cresties will generally (NOT ALWAYS) lay eggs 3-4 weeks after a successful breeding.
"and what should i use for them to lay in"
I use plastic disposable tupperware type containers (Ziplock storage containers) with holes in the side near the top so they can get into and out of there. Then I put 3-4" of 1/2 vermiculite and 1/2 soil. Check this DAILY for eggs...and remove them.
"and what should i use to incubate them in. Any advice on incubation setups and techniques would also be appreciated."
I use sweater boxes with a couple of inches of vermiculite in the bottom. For 200g of vermiculite I use 100g of water. Weigh the whole thing. When the weight drops by 20g I add more water. I have a series of 1/8" drilled hoels for ventalation for the lil ones, but still holds in alot of humidity.I just incubate mine in a closet. room temp (around 72-74 F). I just started doing that after in the past keeping them warmer. I am wanting to see if I notice any difference in hatch rates or sex although the general thought to date is there is not a hard and fast PROVEN way to control sex with temp.
I hope that this helps you.
