I am new to Backyard Chickens but, I have had Chickens for some time now with my son. I use to do West Nile Virus, Encephalitis research here in NJ years ago. I would go to satellite farms and collect blood samples to test for the viruses. I took the pictures of the chicks after a couple of days. The next set of pictures were taken a couple of months later. I would like to see if anyone can match the CHICKS TO THE PULLETS/ROOS. Let your KIDS see if they could also. Just trying to have some fun...........GOOD LUCK !! I will post the answers later. Match the LETTER to the NUMBER. Thanks and Create a great day !
