yes, I had searched every where for sharp edges. they re injured same areas. a game camera is an option. also my neighbors rooster is approx 2 years old, my birds will be one year in july. I'm still thinking about if their space is sufficient. Update, went out this morning, the 2 injured birds safe and sound in isolation cage. No new injuries on other birds. So 2 in isolation and 5 others. let them all free range for a while last night, no fighting observed and they all were on perches before I removed the 2 to their cage.
