OK - I've got 1 barred rock, 1 frizzle & 1 RIR rooster. I just yesterday had to put down my other barred rock due to a nasty leg injury, but that is a different story. I also have three Buff Orpington chicks about 9 weeks old now that are ready to join the flock. Here is what I've done so far. - Today was cleaning day so I cleaned the chick brooder (large dog kennel) & took some extra fence & built a temporary pen in the garage next to the brooder for the adult birds. I have now brought the three adult birds into this pen so they can see & hear the chicks etc. They cannot yet get to each other. Tomorrow I will scrub & disinfect the coop & separate a small section in the run where the chicks can get & the others (except the banty frizzle) can't so they have somewhere to hide when they need to. Tomorrow night I will put them all together in the coop for the first time & will let them into the run Monday morning. Someone tell me if I'm crazy - I'm trying really hard to make this introduction successful & I don't want my roo killing ANY chicks. Should I keep him separate all together for a week or so? I can easily do that when I build the partition. What do you think?
