I'm going to work on a longer report this afternoon/evening - upshot is everyone looks fine, really. Chicks were fed 5 times between the time of the fight and 1300h today, and they both ate each time. Ella isn't showing any signs of being injured, bit muffed up, but not as much as I've seen others, like Princess. And I'm sure her feet hurt a bit, but she isn't showing any impairment - sometimes you see them stepping lightly or what seems like awkwardly, actually it is perfectly normal during incubation and brooding - I keep thinking it must be like having both your feet fall asleep every time you have a nap with the kids. She's flying and bringing in food and using her feet to feed the chicks and herself, so she's not finding the after effects of yesterday's fight at all restricting.
And no, we haven't had any reports of injured peregrines - and I've notified the rehab organizations just in case.
