I have 4 buff orpingtons that I was told when I purchased them that they were already laying. I've had them almost a month and no eggs. they are young (6mo) and I've been giving them layer feed for a month now. I'm little concerned that I shouldn't be giving them layer feed this long and not have eggs. Is this ok? The combs and wattles are starting to get red but still look more of a pinkish color. Should I switch back to starter feed? I could mix starter and layer as I have a bag of both. Thanks and Merry Christmas!
