I can so relate. Although I'm not doing any shipping, I do have many different age groups in different pens and I just hatched a batch of delawares and columbian rocks this weekend. I have 3 different age groups with my New Hampshires and it's looking like my last batch was mostly roos. I think I'd like to hatch one more batch but I think I'll wait for a broody hen and let her do all the work next time.
Hey Ben, that doctor's appointment is still open. ha,ha
