I have a week old Columbian rock pullet that's been lame on her Right foot since I got her 5 days ago. I've noticed swelling increase in that foot the past 24 hrs. I have clindmycin and metronidazole, and tylan injectable to use if needed. What do you all think. She is non weight bearing on it and often stands holding it up. Lays doen alot. I have cleaned it several times to check for any wounds or wholes and found nothing. No blackness noted after I clean it.
