Does age really factor into breeding much, or is it all based upon size? I have one little girl who has grown ALOT over the past year, and i've never bred anything under 2yrs of age. Currently, she is bigger than my breeders and she is only 1yr old. She is my absolute favorite, and i want to mix her back with the dad (who is albino) and see if i can't product some more albinos with the same temperment she has.
I'm a little impatient, but i didn't want to try and breed her if it could potentially hurt her any way which could be avoided. I've heard of people breeding at a young age but i'm a little skeptical.
Any advice would be greatly appreciated, thank you!
