He didn't come in to roost Saturday night, so I think his attack started Saturday but we didn't find him until Sunday.
There are several things I would have done differently if I would have found this board sooner.
He has not eaten since the Monday. I should have offered him yogurt, cottage cheese and/or hard-boiled eggs while he was still strong enough to eat. At this point I don't think he could swallow it.
I would have put him on aspirin and Gatorade (or other electrolyte supplement) right away.
He would have received a shot of antibiotics immediately.
His external wounds (which we treated with Corona, a topical ointment) have not been an issue. They are actually healing very nicely.
I'm not beating myself up with "should've" or "what ifs" here; what happened, happened, and that can't be changed. Basically I'm just condensing suggestions that I have received and information posted in other threads.
I know those critters were here before people started populating this area so heavily. I really can't blame the coyotes for doing what comes naturally to them. They are running out of habitat in this area ... and they still need to eat. That doesn't mean that I have to provide the buffet for them.
I'm going to raise their outside run fences to eight feet, bury some wire at the fence line and run a couple strands of wire. I am also toying with the idea of getting some guines and a baby monitor. From what I have read, motion lights won't scare coyotes away but I am wondering if motion-activated toys (think Billy Bass, Buck the Reindeer, etc.) would do any good.
Please don't think me ridiculous when I say that if any of the information in this thread can help save the life of another chicken, poor Ol' Red won't have died in vain. No, he's not dead yet so there is still hope, but I really don't expect him to make it. I think he's just too weak to pull through this.
