I have 3 week old chicks so I'm still in the planning, trying to find homes for roosters stage. One home I found for a Golden Cuckoo Maran cockerel I hatched, is a country home with hatchery purchased pullets. I'm assuming the hatchery chicks had some kind of misting with vaccine and egg injection. My chicks I hatched from eggs have no vaccines. So the question is..... are the vaccinated chickens dangerous to the unvaccinated little cockerel? Is any of the stuff they get vaccinated with going to infect the little guy? I don't want to doom these guys I'm giving away and need to know what to do for them. thanks for you help....... Oh and if any one wants a Barnevelder cockerel or a Golden Penciled Hamburg cockerel, both from good lines..... I'm sure I have one for you.
