You will definitely need a car if you are farming. Preferably a big powerful diesel that can tow a livestock trailer,and for fitting sacks of feed, bedding,bales and fencing posts in.
Are you prepared to have no holidays or days out,unless you can find someone reliable,experienced and affordable to look after your animals?
Are you happy to work 7 days a week,no matter how ill you feel or how tired you are?
We have a 200 acre family farm,and out of the 7 family members working on it,only one person is paid to do so. The others are in their 70's and 80's and have pensions,or are in their 50's and have another job or even two to survive. And this is a farm with no mortgage or rent.
I've just had to stop typing and run outside,because the lambs have escaped. This morning,I had a horse hopping lame,a farrier due to see her at 9am whilst I had an urgent hospital appointment 20 minutes earlier in a nearby town. I had to call in a favour to get someone to be there for the farrier, otherwise I'd have had to cancel one or the other.
Animals are unpredictable, expensive and can be dangerous if you don't know what you are doing,and they like to injure themselves on weekends and bank holidays when the vets call out fees will be out of hours and ££££. That's if you can find a farm vet,as a lot of practices won't come out to farm animals any more.
Land does not look after itself,you will be forever fencing,hedging,putting new gates on after your old ones were stolen,rolling,harrowing,reseeding, weed killing and ensuring that your land does not become poached,because if it does,DEFRA will come along and fine you for it.
Getting some training at an agricultural college and or working for someone else is your best bet. Then you will have set working hours and time off,without the continual worry. Our local cattle market often has ads for farm workers wanted,so jobs are out there.
