I don't think there is a problem finding adult females. The problem is finding adult females, CB, over 1000 grams, and CHEAP!!! It's the additional criteria of being CB, feeding on frozen thawed, CHEAP, etc. that narrows down the available group to almost nothing. I've posted females only, with good weight, feeding, clean inside and out, etc. only to receive some rediculous offers. If you expect someone to give up a healthy, feeding, near breeding size adult, you should be willing to pay. Afterall, didn't they go through the same efforts that your complaining about. They had to shop hard and long, pay a premium or work with it for a year or more to get it up to size.
It is frustrating, been there, done that! Keep shopping or get some younger ones, 400-800 grams and feed them all they will eat so you can try next year. Also, consider paying a little more. Isn't it worth a little more to get your hatchlings to market a year or more earlier?
I recently offered a group of females to a breeder that has just invested thousands of dollars in various morphs. Instead of paying me $150 each for a couple of very nice balls, he opted to buy '04 CH at $10 each. It will probably be spring of '06 before they are ready to breed. My females will be ready next year. Also, he has co-dominant pastel males that will be ready next year. So he saved $140 per female and will lose more than that, a lot more than that per hatchling pastel because of market changes. By the '06 breeding season pastel pricing will have dropped more than his savings.
Sorry for the rant!
