feed yard cost

[xbred]

I'm thinking of holding my calves this fall and retaining ownership..what would the aveage expense be to feed out 70 head of 700lb char x calves (50% strs. -50%hfrs.) at a typical feed yard..they will probably bring .95-1.00 lb. avg. now avg after fees $650.00 per hd....
background feed and vac. for 45 days at $125 hd.
Trucking cost
medical cost
feed
yardage?
other expenses??
