I bet it will. Our rooster Sam has been through more, "learned the hard way" predator accidents than I can count. Before this site, we lost a lot of birds due to not doing enough research. :hmm I am of course I am always guilty of that, but on the plus side, it has shaped multiple survivors. Sam...
I've also heard that Guinea Fowl will sense predators and alert the chickens, but I'm not sure if thats just for ground predators, arial, or both. Or if its a trait that all Guinea Fowl have. :confused:
I would assume that the newly bare tree was what enabled the hawk to get to the birds since there usual shelter is down. Smart birds will see a hawk before it sees them. Without there usually shelter, its possible that even while hiding the birds were visible to the hawk.
I wouldn't count on...
