I think your trying to do too many things at once, like I was when I first started.
Most "cow/calf" operations sell calves at 5 to 8 months.
Those calves sell to a "backgrounder" or "stocker" to run on grass usually. Sometimes wheat or oat pasture depending on time of year.
They grow em out to "feedlot" size and most times sell to feedlots or at auction to someone who is buying for a feedlot.
Doing all three of those things before you sell requires a LOT of inputs and land!!
Pick one thing and do it well!
