We have two roosters and my Deleware has been crowing for 3 weeks. Finally sounds like a rooster. My EE just started today, sounded pretty sickly. I went to the coop to watch and it was like the Deleware was teaching the EE. Really neat, the Deleware would crow and the EE would....well try to crow, back and forth it went on like a teacher and student. Now the fun begins. LOL.
