Cally update
Thanks to everyone who wrote to wish Cally well with her recovery! You are all too sweet. She is at the vet now getting stitched up; we'll be headed out to pick her up in an hour or two. The vet said it was good that we brought her in because it would have gotten maggots, especially during this time of year. Yuck! He gave me the option of treating it with antibiotic ointment or having him sew it up, and I decided the stitches sounded like more of a sure solution so we went with that. I would have felt bad smearing ointment into her open sore several times a day (sounds painful), plus I was worried about her picking at it or one of the other chickens pecking it or something - I think this will hopefully be a more comfortable solution.
