Thanks, BG and Melsta, i thought as much about the EPU as the method of checking egg quality.... just wishing someone clever had thought of a less invasive technique!
Thanks for your support Melsta - i'm actually home at the moment, which is nice..... i'm officially 'looking for part time work', but in reality, i'm busy painting our study! I love painting, as you get instant results, and i have a whole house that needs painting, so i'm in my element and it feels good to be doing something constructive!! Best wishes
