as the title goes Looking for some pictures and some suggestions dos and donts on a permenent sheep handeling system. The system needs to handle up to 500 ewes with lambs it would possibly be indoors and have approx 120 ft x30 ft to work with it needs to include a race as long as possible. 3 way shedding gate and pens both sides of race to hold about a fair amount of sheep the ewes would be gatherd to a coral that feeds this working area.
