I have had a bad batch of chicks which only 7 survived after finding what was wrong and medicating them. I bought some more to supplement my loses but they are 2 weeks apart. There is a big size difference and I dont want the older chicks killing the younger. I have been medicating the new chicks with Amprol 128 and they seem really health. What I am thinking is adding them to the same broader but using chicken wire to separate them. Wait a couple of days then remove the wire. Any ideas?
