I have a 4 yr old son who I really want to get involved with this and I was wondering how old they have to be and how I could get started on this. Any 4 H members out there that can help me? I am getting show silkies for him Saturday and I want him to raise them, take care of them and then show them when they get older. It would be a fun thing for him and I to do together. Is there costs in getting involved in this? What are they?
