And it tells us something with Roosters as well. The redder the comb, the more sexually mature and active. .....Since we put Abe into the breeding pen, his comb and wattles have really reddend up, much more so than in the past few months.Not crazy at all! Redness of comb and wattles are definite indicators of readiness to lay, even from one day to the next. I observe the same with my hens.
