Major score, found these free on Craigslist! The gal said they were 3 months, but they are about the size of my 2 month olds. Can ya help me ID them, please? They are in quarantine in the big brooder right now. How long for quarantine? 3 or 4 weeks? The first appears to be a leghorn, the second I was thinking maybe red sex link? The next two are EE's, and the last the gal told me was a mystery chick. It is black with some brown on it's chest.
