I'm a bit cheeky when I go to the vet for example If my dog has to go but my mum's cat has to have it's routine stuff tick, worm ect I take them both and get away with one consultation fee! And if I need sheep advice I ask at the same time,
I also email information for example FEC results to the vets avoiding an appointment and consultation fee
As it cost £32 to have a ewe lambed last year plus £25 call out! ( and a dead lamb) Jags now I buy a bottle of penicillin or emgimicin and jag everything myself. (ask for a long use by date)
I also invested in hippie scub £7 a bottle to treat all minor wound infections, bites, I also now clean the lambs years before I tag them to hopefully prevent any infections, sores in my show lambs as sowing up ears are never cheap!
If it's nothing serious ie castrating a funny lamb, ask the vet to pop in next time he's PASSINGand they should half the call out fee!
You can save so money I have the vet was making a fortune of me
