A friend gave me six chickens. She has a closed flock. When I told her last week that I'd take six, she put them in a "quarantine" pen away from her flock. Actually, I told her I'd take two but chicken math happened. Seven days later... I picked them up tonight. I went after dark so they would be calm. Also, I wanted to check for bugs. No creepy crawlers and they look like they are very healthy birds. So tonight, they are in with my eight, but not where they can touch each other. They are in wire dog crates but in the coop. I sprinkled Sevin under their crate just in case, gave them pine shavings and off to sleep they went. New birds are probably 10-12 weeks old. I think mine are about 6-8 weeks. What is the best way to let them meet? Ideas I've come up with: 1. Introduce them one at a time. 2. Let all six newbies in but thought this might be overwhelming. 3. Create mass confusion by taking out several of mine and switching them up with adding the new ones and eventually combining them all. Any suggestions?
