I bought a Silkie about 3 months ago thinking it was a hen. This morning I come to find that it is a Rooster. Walking out to the coop the the sounds of " cock a do a doo" he only crowed 6 times and hasn't crowed all day. BUT he has been making this weird noise. it sounds that a cawing noise. He is in a pen with three other hens.. I am not sure if this is a mating call, or if this is just normal for a rooster. He is showing no other signs of a Rooster. No crown or redness near his mouth or head... I don't think hens and make crowing noises... Just wondering what this Cawing noise is????? AND why he hasn't crowed all day only a couple of times this morning and that was it????
