you have to be really lucky to find them under seven days
I did but just as I was leaving on a trip
Just checked for the Julian date on my carton (boy.....am I glad I saved that thing....) and it is "100". So that means they were collected on April 10th. I bought them on 4/23 at 13 days old and set them 4/25 at 15 days.
BTW @ozexpat ...thanks for posting the Julian Calendar.
