Crows

We've got a 'family' of 5 here that share the chicken run. Once they cottoned on to the free buffet that was it....they took chicken citizenship I only have black hens, so maybe they felt that they blend in well. It's quite comical to watch them strutting around with the girls. As for the cats, wary mistrust on both sides

 

Not crows, but thick billed ravens from Ethiopia; omnivorous yes, but it did seem the more disgusting the better though.
