I finally got my 4 couple day old chicks on Tuesday. An Ameraucana that is a few days younger became available and I'd like to add her to my other 4 chicks tomorrow. My girls are calm and get along well. They don't boss or push each other around, or peck or pick each other. They have plenty of space,and have dirt and sod to scratch around in for enrichment. Have the girls established any kind of social order at this point that might be upset by a new bird? I would hate for someone to start getting picked on. Thanks so much!
