So your suggestion is to add a male (have two males total), or take a male away (have zero males total)? Sorry, but that does not make any sense. :) Also, the males have little to nothing to do with egg laying unless the males are harassing the females (usually if you have too many males). If the males are not harassing the ladies, having one male to 4 females, or one male to 4,000 females isn't going to make a difference in egg laying.
Edit: There are some studies that show that an immature female hearing or seeing a mature male can cause her to develop to maturity slightly faster. But there is nothing I know about that says having one male to 8 ladies is going to somehow impact their laying patterns. In fact, the vast majority of opinions seem to say that a good ratio is between 4-8 ladies per male if you want to still have good fertilization, but also reduce aggression. Adding another male is not going to change anything for the better, and depending on how aggressive the new male is, could actually make it worse. Removing all the males is an option, but if the ladies start laying when he is gone, I will guarantee that it was pure coincidence :)
