Hi- I'm new to raising chickens and have 2 4 month old RIR's who lay and 'own' their coop. My question is, I have a solo Buff Orp chick- about 5 weeks old who I would like to move into the coop with the big girls. She's lonely. Of course, the RIR's will have nothing for it and attack her if she gets close. What can I do to get them to 'all get along'? How old would you recommend the chick to be before introducing her to the coop? Also, we have been trying to find another chick for the BO- is there a breed you recommend? All we can find are new born chicks- can we house the newborn with the 5-6 week old? Thank you for any advice!!!
