Welcome to the group Helen, exciting times ahead for you
.
Sorry to hear about the hen and chicks, hope you can overcome that, but the pigs sound to be doing well?
.
Deer are a nuisance here as well, causing problems with trees planted some years ago, they used to go for the ash, but that is dying off now?. I have read that you can hang things round to put them off, soap, human hair, or old socks. I found when my goats were eating a willow I sprayed it with a weak solution of goat manure/water, put them off for a while.
