your girl needs to be crated in a room apart from the males (and they should have no access to this room) nothing you otherwise do (short of sending the males to a friend's home for 4 weeks) will stop the boys from breeding her when her peak time comes. NOTHING

males will scale fences, rip through flimsy wire, eat through thin walls and doors and more to get at a female in heat.

Best option is the above PLUS have her potty in an area the boys do not go so they are not exposed to her urine etc..
