You are very, very lucky
. There is a fabulous small slaugherhouse right on your doorstep and they are very helpful with newcomers. They will tell you which day of the week to bring them in, and charge approx. £27 for kill and butchery, with each animal labelled by weight. If you do not need the meat bagged and labelled, ask for a 'farmers pack', and it will be in joints but not labelled, and each animal in one large bag.
There are no signs on the road, you would never know it is there
I will pm you the contact details.
