We had 22 chickens, 3 of whom were roos. I knew we needed to cull, but the two roos were the other roo's children so dominance was established. Tonight DH came in and said the 4 roos were fighting too much. I said 4??? So I go out to see what's up. I find a big hole in the fencing of my run. 19 chickens one of whom is a brown roo I have never seen in my life!!! What?? Thoughts? What the hey happened in my coop today?
