I have 2 Welsummers that are 8 months old. I just brought home 4 more 10 week old Wellsummer pullets. Both the existing Wellies and the new ones have been vaccinated for Marek's and Fowlpox. I have my older girls in a coop/run and not being allowed out at all (because as we all know, first thing they'll do is run up to the New Girls and check em out). I have the new pullets in a separate run/coop that is 175 feet away. All food/water bowls as well as both coops and runs have been treated with Oxine. I have separate shoes for each coop as well as changing clothes between caring for each group. My plan is to put the two coops next to each other after QT so they can all get to see each other for a week or two before I merge the two flocks. Barring any health problems that may come up, how long would be recommended to keep them separated in QT before moving them close together? Am I missing anything that should be done during the QT process? The new girls are on dirt, so they'll be getting exposed to any cocci or other things on the ground and hopefully build resistance.
