Is it possible to introduce a new ASF female?

[Shanna]

I ordered a 1.2 ASF breeding trio from my pet store, however my order came in as 2.1. I refused the smaller male and I have a 1.1 breeding pair. The pet store is suppose to order me a 2nd female, however it's now been 3 weeks. I've read that there can be fighting and possible death if a new doe is introduced to an existing colony. I've also read that if I clean the tank and dab vanilla extract on their noses and/or bottoms that they should accept the new addition.

Also, housing wise, they are in a 10 gallon tank with metal screen topper. They have a wooden house, water, aspen bedding, 2 toilet paper rolls, food dish with mazuri rodent feed, and once a week I toss a carrot in there. I keep the front of their tank covered (mostly because I have a too curious cat).

I plan to feed offspring to my BPs. I have two 2012 females, an adult male, & plan to add 1-2 more BPs before the year is up. The plan is to euthanize then freeze extra weanlings for later consumption or trade them to my petstore for crickets for my beardie (the pet store has agreed to do this).

What are your thoughts on this? Should I leave my pair as is? Or wait for them to have their first litter and hold back one of the females to complete my breeding trio? Or should my pair be able to supply enough for the amount of snakes I have. I am new to this and would appreciate the expertise of the experienced members.

thanks,
