Will I be able to get this girl to breeding size?

By late this season she is 827g and pounding weaned rats every week (she is a 08)

You'd have to up her food intake, which isn't a bad thing if she's only eating weanlings weekly at over 800 grams. She'd do small rats with no problem right now and could take medium rats very soon.

I have a 1000g female I want to get up to breeding size this season and have thus started breeding rats.

I would suggest offering 15-20% body mass in food/week to get her to gain weight, at that percentage she should reach 1500g in a relatively short time, from there you can bump her up (I would go to 1800g) and then reduce the amount you feed her to 10%, giving her time to grow/lose fat. This is what I intend to do to get my girl up to size. Then you can start trying to breed her when you feel she is both the proper mass and body fat%.

Doing 15% will get her up to size slower, but she should still make it there. Even at 10% you're looking at 80-150g/week, at 80-100 she should be able to hit 1000g in a month or two, then at 100-120 she should bump up to 1200g in 2 weeks to a month, then at 120-150 she should hit 1500g in a month or so. Thus by around december she should be breeding size, but I wouldnt just breed her the moment she hits the right size. So, January-March you should be able to put a male with her and probably get eggs.

Oh, and may I suggest getting her up to 2 rats/week, she should get used to double feedings and it's easier to get the right mass by adding 2 rat bodies together than by finding 1 rat of the right size. Plus it will be easier to swallow.

Id deffinetly up her intake or size. Maybe both. I can feed my 560 gram male a small rat no problem.

Yeah, up to small rats. But don't power feed her or try to force down large prey items to try and get her up to size. Better to have her get there for '12 and be a healthy size, than to force her there for '11.

I should probably have added that, yeah if she doesnt want to eat, dont try and make her, and dont feed her by following one after the other (face to butt as it were) to power feed her. I'm simply suggesting offering her an increased amount of food that is not unreasonably so.

Large weanlings ever 3-4 days ;)

I bought my pewter female at ~900 g last August and she was up to 1800+ when I started breeding her in mid December. All I did was feed one small rat a week until about the middle of November and then upped it to one small rat every 5 days.
