depends on his bloodlines.as well as what hwe looks like at 6 months old.but id say $900 is a fair price for a reg hereford bull calf.i sold reg beefmaster heifers that was 6 an 9 months old for $800ea.
If the breeder has the blood and reputation behind him, I'd say you might even be approaching the $1000 mark given a yearling market approaching $2000.
