Hi guys, I have 2 egg lying backyard chickens. they are sisters with the same age and now they are around 1 year old. and now I wanted to get another pullets for the same purpose. So i bought 2 pullets which are 2 months old but when they reach 4 months old one of them gets a bigger wattle and comb. I was confused at the time but when they reach 6 months old I ensured that i got a cockerel and a pullet. Amazingly I was about to buy a rooster for the hens to provide them protection and let them feel natural. so i was happy at the time but the old hens doesn't like the cockerel and they just want to bite and peck him always. So I separated their house (coop) they are just free ranged so they can even go out side to the neighborhood.The young pullet just run from the old hens but the cockerel doesn't want to go away instead he just stay when they bite him but doesn't do anything to defend himself he just stay on his ground but if they get harder on him he will run like the pullet. now he is 8 months old but he is still hasn't changed and even he is not crowing and when I try to catch him he squats submissively like the chickens but the thing that makes him different is he bites me when I touch him for longer time. The young pullet is not friendly like him she just run when I try to catch her and she also doesn't start laying eggs. So do their breed matures lately? If not why is my cockerel not acting like matured?
