How is their temperment? The feed store guy told me they can be grouchy, T or F? I love my orp, thinking about either adding australorps or ameraucanas, WWYD? A little confused on the colored eggs thing, will they only be one shade if there is no fertilization (that was kinda the impression I got from reading some other posts the x is what influences the shell color, is that right?) Sorry if these are stupid Q's. I appreciate any help.
