Growth, weights, etc...what is normal average?

I just recently got a scale...since tonight is feeding night I weighed everyone earlier today. Now I'm wondering if I am feeding enough...can someone remind me what the formula is to figure out size of rat based on weight?

My oldest girl, Cleo, is about 5.5 years old, I was a bit surprised when the scale told me 1160gms. Now, she is my problem child in regards to eating, in fact just came off a 5 month feeding fast (think she ate once somewhere in the middle) but has slammed the last 2 small rats I've given her. Before her fast she was taking medium rats but I went back to small after the fast because she kept refusing the mediums. Any suggestions?

My 2 smallest girls were tough to get going when I first got them...the Feb 2016 girl, Meri, is now 167gms and the July 2016 girl, Isis, is 116gms. I think I spent the first 2-3 months praying for them to eat. Meri still doesnt like anything too big, so I really walk the line with her. But they both usually eat like clockwork now.

Then the middle 3...Ramses (8/15) weighs 420gms. Seti (8/15) weighs 343gms. Nefertiri (12/15) weighs 336gms. Ramses is kinda the piggie...if someone wouldn't eat he was always willing to be the garbage disposal.

I feed weekly, f/t, and all rats...so anything I should/could be doing different?

There is no range and you should not go by weight, I have 2016 females anywhere from 400 grams to 1100 grams and there is only 2 to 3 months age difference between them.

They grow at different rates and there also other contributing factors between animals, size out of the egg, how fast the animal started to eat out of the egg, prey size, feeding frequency etc.

What matter is a healthy animal that is eating appropriate size prey and that is well proportionate.

Thanks Deborah, that relieves my mind somewhat, although your 2016 seem to be almost 4x the size of mine...lol...honestly the scale surprised me... I thought for sure that Isis was heavier than Meri...but Meri is very long and slender with the tiniest little head!
