It works for him, I give him kudos for having the balls to try it and see what works for him. Just from reading Jas' posts I can tell he must be deeply in tune to each and every one of his animals, and I'm sure if he deemed it unsafe to breed a particular animal he wouldn't. I really think we all need to step back before jumping all over him about his breeding practices.
Isn't it also true that if a female wasn't ready or mature enough to reproduce she wouldn't even develop follicles/eggs, or just plain slug out. I understand there could always be a threat of a small female becoming egg bound...but a BIG overweight female could become egg bound just the same.
Do what works! It is one thing to read about doing something...it is another to have first hand experience doing so.
Rock on John!
