So i have these two older chickens about 4 months old. What gender do you think they are? And can you judge the breed ? The black one, Rohan, didnt grow a tail till a few days ago miraculously. Also, i got them on 10th march so that makes them about 16-17 weeks old. The brown one hasnt got a big comb, just a pink small comb. Any idea when , if a hen, any will start laying? start laying?
