Welcome to R2R! I was out of the hobby for 13 years and just got back into it in the last year. For me, the hobby has changed a lot, progressing for 'the better', but changed none-the-less. My advice is to do a lot of research and ask a lot of questions. Sometimes I feel stupid asking basic questions, but I'd rather ask a question and get the best answer/result, than not and waste my time, money and/or sacrifice livestock. I am enjoying being back in the hobby. Good luck!
