Hi, I have read many of the threads here about vaccinating or not vaccinating...I still can't get a real good feeling about it. So I thought you all can help me out. So I am thinking of buying some light Brahmas but those guys have been vaccinated for Merek's( sp?) but my chicks that I have are about going on 2 weeks 2 are almost 3 weeks and was wondering if I should buy the Mareks vaccine for these guys too? I know I read somewhere that 3 weeks is pushing it right? So my 2 may be too late? I live in California on the Central coast. We do have neighbors who have chickens as I hear roosters all the time and my sister in law who will live accross the way will have chickens too from the same batch..what dya think? I would hate to lose my whole flock. I have now 16 chickies.
