I am planning on chickens and only in the sketch phase of the coop design process. Just because I am not planning on acquiring chickens until spring does not mean that I am not window-shopping the breeds. Can I have a happy flock if I acquire one each of different chicken breeds? I understand that it is not advisable to have an "odd man out", but if EVERYONE is different, will they be happy? .....or do they really need "birds of a feather" for psychological well-being? I may very well prefer to pick a single breed, but wanted to check my options. Thanks in advance for any help.
