Not knowing what " those shelters" are it is hard to say ! What they need is something to break the wind, even a 3 sided shelter which they can access during the blowing cold winds. Some times the longer ears( I have seen thin ears on some ill bred donkeys) can suffer from frost bite if they cant get away from the winds and wet. I have always preferred wooden buildings for livestock.

The Shelters are very strong.They keep out rain wind etc. The life of one is 10 plus years. We have been seeing farmers all over the country side use them. I live where they need to be protected at night. Also where i can put in corrals. Thankyou for the advice. Jenny

Jennybog, which shelters, exactly, are you referencing? Can you provide a link or a brand name?
