Ya I'm thinking I'll make the call when we get to that point depending ding or prices and how they look. Not sure if it will be the case at that time but here you don't really want to bust your target and go much over 600. There is a pretty big dip in the price per pound some times.
The difference in the #12 vs the #10 pound represents on more feeding basically. Instead of 6 refills, it would be 7. Dollars wise, it's $33 per head for every 2 weeks you keep them.
If a person had a scale, I could weigh them and know their gains for sure, especially in that last 30 days, and decide if the pounds of gain is worth more than $33. There is a scale about 15 miles away, I would just have to load a few and haul them if I really wanted to.
