I have 60 acres of native pasture in Commerce,TX and wish to add 10 +/- cattle this year. Not very experienced with livestock and first priority is calving ease. What type of cattle should I purchase (stocker or registered)? Bred heffiers, open cows w/ bull, heffiers w/bull or other. Will have access to plenty of hay thru winter. When and what should I buy? I wish to grow herd. Any thoughts will be appreciated.
