Sounds like it. I had an attack on Saturday evening. I found my coop door open (my daughter forgot to shut it for me when I was out of town :-( ) and 2 younger pullets were dead and a cockerel were missing, and two of my laying hens were dead. The surviving 8 birds all have wounds of some sort on them. They are all locked up securely and I am doctoring them and feeding them. Some are less traumatized than others, so they are still laying. 4 others are not at the moment. I think it was a dog or a raccoon. Whatever went after them did so without being picky about what they attacked or took. Only one bird totally missing - the young cockerel. Sigh. I'd like to throttle my daughter, but she feels bad enough as it is.
Glad she showed up ok except for her sprained ankle. Good luck and have fun...
