I have been raising 3 chicks since they were 1 day old. They are now 4 weeks old, and my RIR is obviously not a pullet. I found her (er... him) a new good home with a friend who has 50 chickens and said one more rooster would be just fine. Now I only have 3 chicks. My question is, if I went back to the co-op and picked up another chick, would the 4 week old chicks bully/pester her? Should I just keep the 2 I have left and wait til next year to pick up a couple new ones? The 2 that are left are a Plymouth barred Rock and an Americauna just in case breed temperaments are a factor.
