To be clear:You cannot both add and remove cubes in a single turn. This is expressly forbidden by the rules. If you activate the Breeder 4 times (for example), you can add (up to) 4 cubes or remove (up to) 4 cubes, but not, say, add 2 cubes and then immediately remove them.
While the rules aren't crystal clear, the way my group has played it (and the way I believe it was intended) is that you can either add cubes or remove cubes regardless of the turn - again, you can't do both.
My question was about the rules saying you can add cubes "on the first activation," but my playgroup has chosen to ignore that and play that you can add cubes when activating it, even if it isn't the first activation.
