I feel dumb asking but I'm trying to figure out what to vaccinate my 16 RIR pullets. They're currently 4 weeks old and eating purina medicated chick starter and I'm not planning on getting anymore additions. I have them outside since the weather has been in the 80s and their feathers are almost out. We live in an agricultural area and I haven't seen chickens in my neighborhood, but I occasionally hear a roo. I know for sure the fowl pox is one of the things I want to treat them for (my dad is pretty serious about this disease). Does anyone in the south Florida area have any other issues with certain diseases in the area? I'm just trying to research before they're 6 weeks old. And even if you're not in the area and you have any suggestions go ahead and give me some advice. My brother and I have gone through hell making their chicken mansion and securing their entire run with hardware mesh. We're seriously in love with these girls and I'd never forgive myself if I could've prevented their death with a simple vaccine.
