Bought 2 Australorp's yesterday. We have 9 golden Comets about 16 weeks old. Australorp's are the same age. Will be picking them up Sunday. They are good looking birds. I will Quarantine them for 2 days before putting them together and give them a dust bath. Hoping they get along OK. All are Hens. I was planning on adding some more roosts the same day I put them together.Thinking this will give the newcomers a place to roost without stepping on anyone's feet. Was also thinking of getting some Bantams and adding them into the flock at a later date.(Not so much for eggs,but I like the way they look,,,maybe even 2morrow) Any tips on this?? I heard the bantams might be aggressive. Bought the Australorp's from the GCF,,,Michigan. Is there anyone here familiar with that??
