Can everyone agree on how to tell Plymouth barred rock chicks apart? Here's what I've read on pullets - - will have black on fronts of legs and feet - will feather out more quickly - will have distinct spot on their heads - the head spot will be white? On roos, I've read - - slower feathering - a grayer barring than hens - will pull up if you gently hold them upside down by their feet?! Any other hints or tips? Three of my chicks have yellow head spots - one has a white spot. I need to give two of my four away to a friend in a couple of weeks and I don't want to give her a roo. Thanks soooo much!
