I have a chance to use some land next door that is all fenced in and has water. The only thing is I can only use it in the summer so what goes on it must be sold in the fall. I am thinking of buying some stockers in the spring put them on there for 5 months then sell them at the sale barn. What breed would be my best bet for this situation? They will be getting grass and minerals only. They will also be on there own alot ie. limited human interaction. Also would you buy an older cow or two to put in with them?
