I was curious how big follicles get before a female will actually ovulate? My female has been off food for 3 weeks now and her follicles feel like they are about the size of a bouncy ball or a shooter marble. Do I stil need to leave the male in or is she good to go. I know all females are different, but, I remember reading somewhere that there is a general rule of thumb on follicle sizes and ovulation. Thanks.
