Chirping
I have a pullet that survived an attack...she was partially scalped and had a punctured eye and a punctured ear drum. Brought her inside, cleaned the wound and applied Vetericyn, and kept her in until things had scabbed over. She wasn't eating for me, so I thought she might do better with the flock. It took a bit, but she's completely healed now...she's not quite "right in the head" compared to the others, but she's a sweetheart. Call her Snowflake, 'cause she's special.
The curled foot could be injury, infection, or nutritional deficiency so it's difficult to tell you what the prognosis is for that. Try adding vitamins to the water if you haven't already, just in case.
I have a roo who was attacked by a falcon last week, luckily he only had a small nic on his head because I heard the ruckus and came running
