Hi their, I'm new to chickens so I need everyone's help! I have 3 chickens, 2 Australorps and a Barnevelder. Currently their 16-17 weeks old but haven't laid an egg yet.The Barnevelder has been making really loud noises as loud as a rooster, but not the same pattern as one. I check on her every time she makes the noise but nothing. She tends to do this in the morning but likes to do it at random times as well. I am 100% sure she is a rooster. Thank you in advance.
