I found this forum on Friday and can't stop reading!!!! I have 12 three week old chickens and 10 three week old guineas. I got them to tackle our grasshopper population. So I will be very honest, I have no clue what kind of chickens I have. I ordered the "surprise special st run", and the neighbor says we have some game birds, and looks like three silkies. The boys love looking at the "baby birdies" in the brooder. Addicted to all of them, and can't wait to let them free range on our nine acres.
