First off, while I have not lost chickens to coyotes or foxes, my friend lost her entire flock to them. Foxes have a tendency to kill several if not all of a flock and only eat a few, depending on how many predators were in the pack. Sometimes there are no bodies left, just fluff and feathers b/c they take their meal with them. There is a very good section of the BYC page about predators, including those mentioned. Also if you google "chicken predator" the 1st hit you get is an excellent site in helping to identify the culprit, and says coyotes will take a chicken away with them, and if the dont, they will eat it on site. Coyotes hunt to EAT. Dogs hunt for fun. The aforementioned site says also, domestic dogs tend to grab chickens by the butt, while coyotes and foxes go for the head/throat.
Your hens are hiding because they are afraid. i had some raccoon?? issue, and lost a couple birds over the summer. I had 5 total at the time, and found 3 "bodies" and no sign of the roo and the others. I thought they were dead too, and got dragged off. 2 days went by, and suddenly I
thought I heard a crow. I believed my roo was dead, and dismissed it (one of the bodies was of a white roo, Turned out it wasnt mine but my neighbors, and the predator dragged it across the field to my yard to eat it. Then discovered MY flock and realized it wasnt a 1-course meal apparently) Then I heard the crow again, and looked out the window to see my roo and 2 hens in tow. They took off and laid low for a few days till the coast was clear. yours are prob. hiding because they feel safe there, and are unsure about the "outside" I believe they will come back out when they are comfortable doing so, just like my roo and his ladies came back when they felt safe to do so.
I think your best hope to save cocoa is to clean her wound and apply some Blu-Kote. You should be able to get it at a farm supply store like
TSC, or if you have a local hatchery or vet that deals in livestock (not just dogs and cats) If you dont know, Blu-Kote is an antibacterial/anti fungal wound treatment. You need to separate Cocoa from the flock till she heals, or the others may peck her boo-boo and wind up killing her. Chickens love to peck boo-boos of others in the flock. They also love to peck anything thats a different color than its background, such as raw flesh or blood on a white feathery butt. Clean cocoa's wound, Blu-Kote, and keep her indoors for a few days if possible. You can use a pet carrier to house her. Make sure to keep her watered and add some poultry electrolites to her h2o to help with hydration, and give her some cooked scrambled eggs in her food for extra protien and nutrients until she can get on her feet. You may need to slowly re-intro her to the flock after her recovery if they try to attack her after her absence. Hope this helps
PS they also make something called hot-pick or no-peck that will keep the other birds from pecking her. You can get it at
TSC/FarmEx/etc. it may take a bit of time to get her feathers to come back in. that will encourage the others to pick her. Some hot-pick should help with that.
hope this helps.
Also, I know neighbor-disputes can be problematic. But if the neighbor's dog(s) are killing your flock, action needs to be taken. Maybe you can catch the dogs in the act. I know you work, but maybe on the weekend. Or you could put out a live cage trap. If you had to call the neighbor to retrieve their dog that was trapped in a cage in your yard, then they could not dispute their dogs were problematic for you. I would try to work it out with them yourself, and if not, a call to animal control might be the last resort. I believe if the dogs have already found a way to get to your birds, they will be back until you have no birds left.
