I have just inherited (typo edit)* 35 head of sheep and 14 have fly strike.

The local vet over the phone suggested putting them down as the cheapest solution

I need advice on what to do with sheep with fly strike, poor animals are being eaten away by maggots.
How can I treat it, I have already crutched them and used the stuff that was in the shed.
I need serious veterinarian and or experienced advice please.
Maybe in future I should muse them to stop this?
Savage shit but in the long run it seems to work the best. (bit like circumcision)
I know Blackmagic is a vet nurse and I hope she can offer some solution, Wendy please I need help with this....?
Cheers
