Thought I'd better let you know that I'm going away for a month to the UK (mother, sister, daughter and a new nephew I've never seen are all over there!).
My husband (Tony) is left in charge of our pregnant heifer. He's more into face-to-face advice than this forum so you probably won't hear from him. We have two neigbours who are experienced cattle breeders. Tony helped one of them to deliver a calf last year to get some experience and I'm sure both of them will come and help if required.
