How to scare crows away from chickens?
I'm the owner of chickens in our backyard, having a bit of crow problem recently...
We have enclosed chicken run (fenced both wall & ceiling) along to the chicken coop for our girls. We also let them run around in extended fenced area (this area only has wall fence, no ceiling fence) during the day time since the risk of predators are low in this area. They love it! :)
However, a couple of days ago, I found one crow somehow got into the chicken run thru a tiny chicken-size door, couldn't find his/her way out, fleaking out him/her self as well as our chickens who happened to be in chicken run/coop at the time...
I opened the human-size door of the chicken run, the crow eventually flew outside of it... This made me think that I would need to do something about this problem.
I may be too worried, but I heard crows could carry west nile virus. I wouldn't like to have them around our chickens all the time (the reason the crow got in to our chicken run would be to get the leftover food scraps we feed our chickens every morning...).
Is there effective way to scare crows away??
I know regular birds don't like shiny stuff moving such as CD disk on string, but I've heard crows are actually attracted to the shiny things...
Any help/advices will be appreciated!
