Concerning your question about vaccinating or not, I have three Coloured Ryeland ewes which I keep for their wool, and don't breed from, but I still vaccinate with Heptavac P plus every year. The vaccination provides active immunisation against a whole pile of nasty diseases in the adult sheep, with the added benefit that, if the annual booster is given to a pregnant ewe 4-6 weeks before lambing, the lamb recieves passive immunisation to protect it for the first few weeks of it's life. If you decide to vaccinate your Ryelands the initial course consists of two injections, separated by 4-6 weeks and then a single annual booser. Unfortunatly the minimum quantity of vaccine you can buy is 50 ml ( sufficient for 25 sheep!). If you get the vet to come out you will probably still have to be charged for the whole bottle because it is a live vaccine and has to be used within ten hours of being opened. If you do vaccinate now then it would be more economic next year to do all your sheep when the zwartbles are due, even though it would actually be earlier than the Ryelands actually needed theirs. I have had to do just that to fit in with vaccinating my Welsh Mountain lamb that I hand reared. As Yeoman said, watching someone experienced do it first is the best way to know if you would be confident enough to do it yourself in the future. When I first got my sheep I found "The Sheep Book for smallholders" by Tim Tyne really useful but I am sure other people have other books they would recommend. People on this forum are very generous with their experience and knowledge and never make you feel you are making " a fuss about nothing" so enjoy your sheep and keep asking about anything you are not sure of.
