Mineral feeder update

After a few more days of use, it appears that phosphorous was in short supply with my cows. It’s almost time to add more while the other minerals are pretty much untouched still. The phosphorous is on the corner so the rubber is easier to lift but none if the other three corner minerals are being used so it does appear that they are targeting the phosphorous. I looked up what a phosphorous deficiency causes and it wasn’t very clear. Kind of like what is an herb good for, seems like they all cure everything.

I am worried how I am going to move this mineral feeder by hand once I have to go uphill with it. Just going across flat ground its a handful. I’ve dropped 40 pounds this year. I’m starting to find that I cannot just hoss things around like a used to. There is no substitute for mass.
