Looking at the calendar, it's been about one month since our Campine, Shaggy, was attacked. And because of the holidays, it's been a couple weeks since I posted an update.
The update is a good one, the final one for this thread, with a happy ending. Shaggy has fully rejoined the flock. And on Christmas day, about 3 weeks after the attack, she resumed laying. Not frequently, but enough to indicate her health has returned. She has a fairly good, although not full, range of motion on the wing that was broken,and if you weren't aware it had been injured, you probably wouldn't know at at glance.
We've had unseasonably warm weather this 'winter' so far, and that was a Godsend, I believe, in her recovery, because it allowed for them to be outside and free range much of the day--supervised by yours truly, under an umbrella, with a cold drink, pretending it's summer

, and refusing to even think about the ice storms, which, knowing Texas weather, will be here in just a few weeks.
I have only a few years experience, with a tiny flock, but I've come to see these birds as both frail and resilient. In past experience, when one has gone down, due to sickness or injury, we've done everything we can for them. And the heart-breaker is that in most, almost all cases to date, it hasn't worked, and we lost them soon after.
But this time, I'm going to claim victory, resiliency has trumped frailty, and it's very rewarding. As I write this--yes, not kidding, under an umbrella, under sunny skies, with a cold drink--Shaggy and the small flock are nearby, in a cloud of dust (bath), in the raised-bed planters that are vacant for the winter.
If she runs, I do see afterward a very small amount of the open mouth breathing, but she returns to normal within a couple minutes. The vet said that if the lungs were damaged, they would eventually heal over a period of weeks--and to think, with all seriousness, that only a couple weeks ago I had sketched out a plan and where to get the equipment, for making a chicken oxygen chamber. First world challenges...
We suspended the antibiotics and pain meds after about 10 days of treatment--mostly because it was a full-on battle royale to catch her, which risked aggravating the wing injury, and to get them down her throat with a syringe, all while avoiding aspiration.
So it's a victory, a life prolonged, to begin this new year.
Cheers, Y'all and Happy New Year, to you all your fine feathered friends!
