Hello. So, I have 53 birds. All live in one big combined flock, but I have had a viruses there. I have two 6 months old cockerels, and I would better like to find them new homes, but in known places, grandmother etc They posibbly are carriers I guess, so, can I move my cockerel to flock where is only few hens, 10-15. And did I need vaccinate them? How can it help? It specialy to dont make hens sick in time. + I have 11 old rooster from same flock, but as he is a purebreed im going to move he in other closed coop and buy his breed hens. He probably can make hens sicks? He is healthy Vorwerk today, be had got a disease as sneezings , but I rehab him perfectly. Thanks. Sorry for bad language.
