Chickens are very social animals and most breeds do fine together. I live in Florida and have Barred Rocks, RIR, Marans, CCL's, Araucanas, Orpingtons, SIlkies, Seramas and Tolbunts. All of them do fine in this hot, humid weather. I just make sure they have fresh water available at all times and access to shade.I am getting my yard "ready" for 2 chickens. I am sure that I will get a barred rock hen. I am wondering if anyone has any experience with other breeds that do well with a BR? I am looking for a good egg layer and great pet who is able to deal with 90 degree weather in the summer and very mild winters. I am aware that I should not mix a larger hen with a small breed and will not do this.
