We have around 8 roos all between 12 and 15 weeks. So far there were just 2 attempts at crowing (at least while I was home). Once was early one morning, around 4am, and I heard a strange sound that freaked me out. It kept repeating every minute or so, and after searching I finally decided it was a roo attempting to crow out on our porch, very very strange sounding since I didn't realize they needed this practicing phase. Then today it was a polish roo that also sounded very strange. I'm a little excited and nervous for the real crowing to begin! I'm not good at waking up early so probably this will help. I'll have to start getting to bed earlier.
