I should have posted this when I saw it but I forgot to. 1 week ago on Wed. I was outside with my young cockerels and one pullet (don't worry they're siblings and young). I went to the garage to get mealworms and I heard a screaming noise so I thought someone was getting hurt but when I rush back they're tearing apart a small bird! Chasing eachother over the limbs and such. It looked like a finch type bird. I didn't stop them but I'm wondering is that unusual?
