I know this is a old thread but I wanted to say I think this program is very generous and WONDERFUL! I added a meal maker to my order of 7 Barred Rock females. I had some questions about the "meal maker" so I sent a email to Meyer and promptly go a reply. Just so you all know who come across this thread in the future the company had written in their email and told me : "if you have paid to vaccinate the birds in your order (which I had) then Meyer WILL vaccinate your Meal Maker FREE OF CHARGE". I thought this was WONDERFUL!! Also, if you order all females (which I had) then your "meal maker" WILL BE FEMALE. The letters on your invoice should read MMMF. F= Female. as opposed to MMMS. S= straight run.if you see on your invoice MMMS then your "Meal Maker" is not sexed or Straight Run. Also if you ordered layers, you will get a layer ect.Hope this helps someone understand.
