Hi All, I'm trying to figure out how to organize the plethora of chickens I'm about to have. I already have 7 three week old Buffs, who will be moving out to the hen house in a few days. (these chicks have no vaccines, are healthy & on half medicated/half not medicated feed) In just about 3 weeks, I'll have 8 pulletts arriving by mail from mypetchicken all vaccinated for Mareks AND in just about 3 weeks, I hope to have a few from our first attempt at incubation. Obviously, these guys won't be vaccinated for anything. I obviously need to seperate ALL the new babies from what will be 6 week old Buffs, but HOW seperate? Obviously their antibodies are from other geographic regions but they will be raised here... Should I seperate the two new broods from eachother too? even though they will be only a few days apart in age at most? because they are from different places too? Again, how seperate do they need to be? What's your advice on this? Hopefully after this, chicks incubated & raised here will have been born of chickens here and then I won't have these concerns. Thanks for all your input..
