hello home bird, re pigsty make your own! I was horrified at prices as well, we had to make an emergency one when some of the pigs were split up, (ref pig attack) made it out of old fork lift pallets, the tamworth was happy enough with this, they dont need anything fancy. made a perm one out of sheeting dog kennel and scrap pipe,if youve got access to welder even better. ours is on--home made pig arc and some piggys............best of luck neil
