A few of my hens have developed quite the comb recently. I am so impatiently waiting for my first egg. I opened the nest boxes this week. Any advice as to when theyll be laying from the experts!? Here are some pictures of them today. Mable. 18 weeks. White leghorn Madge. 18 weeks. RIR. Maude. 18 weeks. Red Star. Got her squatting in this pic!
