Yeap agree with lots. We have gone from 400 odd breeding ewes to 20 wilts. As a medium size farm with plenty of organic pasture with no issues, no standing water, streams fenced off, worm count no way are we spending or need to inject chemicals in. Good management is better than endless meds.
As for buying in you need to know the land where they have come from. From experience you need to inspect and know the flock. Not keen on Preloved on buying live anything. Better speaking to the local market auctioneer or organic farmers to purchase local.
