I have 7 chickens. 3 orpingtons, a sussex, a cuckoo maran, a rhode island red, and an easter egger. All are approximately 22 weeks and most of them seem to be mature or close to maturity. Yesterday, two of them laid for the first time. I am not sure which ones did because I have heard a lot of mixed information on what age certain breeds lay. Any thoughts based on the information I gave and the colors of the eggs?
