Had the vet out this afternoon to look at my attacked sheep, more to reassure myself as I have been worrying myself sick over the ears that are hanging off and the god awful stench of rotting flesh.
He was really really please with them and said he couldn't believe just how well they are healing! Both the ears are staying where they should be, the Shetlands ear has connected back onto her head and the other sheep still has the normal blood supply feeding it. The punctures to the legs although they look awful he said they are looking good, the animals faces are looking better and he hopes that they will fill back out.
Another 5-7 days of antibiotics plus extra TLC and then they can go back into the group.
I am over the moon and for the vet to turn around and say 'Well done you've done so well' it Is well worth all the tears, sleepless nights and all the hours I've put in so far! It has left me feeling on top of the world!
** Update**
yesterday the police pressed charges on the house sitter (owners were on holiday) turns out she set off to muck the horses out who are on site at 7 am, the dogs were taken with her but she started to muck out and forgot about the dogs and they did a runner for 5 hours! Owners may be liable also as there land wasn't fenced correctly. Waiting for court dates :/
Thank you everyone for all of your advice, without your help I would have been in even more of a worrying mess!
