I got some young chickens 12-14 wks up to just under 8 months. 5 pullets to be exact and one rooster. The rooster crows as expected , as he is older but my question is this. I had some red layers and white ones last year. Just typical feed store hatchlings. These ones are Americauna mix. Just picked them up 2 days ago. Now they were free range so not used to being cooped up. Somebody but not the roo is making a sort of guttural chicken sounding growl.. Almost like a ticked off chicken growl.My other layers last year I never heard before. The grey ones if you stroke their backs they do that squat and wing thing I saw before, a sign of imminent laying will begin. Thats normal. But this isn`t what I expect to hear from their coop. They are in quarantine so by the time I open the door to their coop they all look stupidly at me as if to say `What you looking at`. we weren`t doing anything``I also wonder if it a breed thing with Americaunas. Has anybody heard this vocal behavior before. Oh here they are as soon as I got home.
