I liked your site.I thought your policy bit was rather labour intensive,I wouldn't fancy doing all that,but good luck with it.If you want to promote your site on this site you will have to put a link back to here as it's a forum rule.
The only thing I will say is be very very careful with the studding out of your bucks. I would advise against it, but obviously its your choice. Keep the foreign female no where near your other mice, and once the male has finished doing his duty and the foreign female has gone back home, keep the male away from your other mice too for at least a few weeks aswell.
its a nice idea, but so very risky. You will chance bringing in alot of disease and illnesses.
