Are crows a threat??

[nccatnip]

Yesterday I saw a crow swoop down on my three roo's all standing in the driveway. One swoop and it was gone. Two are big BO's and one is an OEGB. Actually the OEGB was larger than the crow and in all actuality it did not seem to bother the roo's.
This morning, before I let the chickens out, a crow (same one???) was walking up in the driveway looking at all the fallen black walnuts, maybe looking for insects??
I am wondering if crows are threat to larger birds. I know they will eat chicks but could this be a territory issue??

It can be a territory issue, one of my roo's has killed 2 crows this year that had the misfortune to land in his run. They are probably more pest than preditor threat to big birds.

Could be a threat to chics. but any good roo would make it hard on a crow as Rooster said!

crows in large numbers could be threat, there wild, there street smart if you will. My fear in this situation would be the disease factor to your flock. Who knows where that crow ate his last meal. I'd bet a road kill. You've work so hard to keep lice and other pest from your flock, I would work at keeping the crows establishing a comfort zone, near your area.

Its not a good idea to let any wild birds have contact with your flock because of the disease factor.

Crows can also be helpful because they can chase off birds of prey by mobbing them.
I've not had a problem with crows...
I do have to agree with not making it too comfy for them, so that they don't hang around for free eats, like chicks and eggs.
I have more of a problem with squirrels, than my namesakes.

This is so weird to see a thread about crows. Today I saw not once but twice a flock of crow attack and run off hawks. The chicken started this thrilling sound and I heard a bunch of crows having a fit, then I saw them attack and run the hawks away, YoHoo for the good guys.
