So should I not pair them so often? Should I cut back? One of the males is still eating like a champ through this, while the other went off feed about a month ago.
I personally wouldn't pair them that often. Every 21 days is fine it gives your females time to build follicles and time for your males to rest. About the last month before ovulation you can do every 14 days. This is how I do it and I have great results.
