Can any one tell me how long is the average time span from when a chickens comb starts turning from pink to red? Does it go from pink to red in a week, month, etc? I have Light Brahmas with pea combs and they still are pink at 20 weeks. I am just curious to find out cuz I think I see a slight change in color and I am hoping this is going to be a sign that my chickens do know how to lay eggs, right now I am not so sure. Zero, Zip, Zelch so far. grrrrrr Im doing this , but I want to do this!
