An unsurfaced feed lot it is recommended to have 300 to 800 sqft per head , so it would need to be from 1.5 acres to 4 acres in size , it would require 400 to 500 ft of bunk space, it is recommended to be hard surfaced because of mud , needs water and shade, The first thing I would do is to check what has to be done to meet state and EPA regulations to have such an operation , especially if the EPA passes the new clean water act, with each violations being fined $37,000 a day. :cry2: If you have not expressed you disapproval of the new EPA proposal to you local elected official , it is only a short time left to do so, It seems to be strong support to pass the new rule, if passed it will affect all landowners in the USA , and will change the way all farmers and ranch owners operate.
