Impacted Crop? Head rolling? Panting? UPDATED

[sammi]

I would also consider Diane's post about about high weeds and seeds getting damp and going moldy or bad..
doesn't hurt to check the area..

the grit is a good idea..pigeon or granite grit..

and the worming..as threehorses suggested...the initial worming with Wazine..then instead of doing the 10 day retreatment..do the broader wormer.
