Yes I have a baby monitor for the chickens.. The monitor is out in their house and I can hear anything and everything that goes on in the hen house a 100 feet away. I seen a coyote about a week ago out in the front pasture but didn't get a shot at him or her. I live in the country on a 180 acre family farm and have heard them almost nightly my entire life if out sitting on the front or back porch but this is the first time since I have had the chickens and the monitor that I have heard them over the monitor so I guess it was pretty close. I'm not going to worry much over the coyote because I truly doubt it will be a problem concerning the chickens. The chickens are locked up nightly in their sure house. Now Mr. Raccoon is entirely another story and he's the main reason behind the baby monitor and the reason I renovated the old chicken house as well as I could possibly do it. I figure If I hear something going on during the night I can get out there reasonably pretty quick and so far I haven't had to make a dash out there in the middle of the night. I recall one night awhile back the monitor woke me up in the middle of the night and it scared me to death and I jumped up thinking something was trying to get in the hen house. I was thinking the worst until I opened the back door and realized it was a heavy rain that was hitting the tin roof of the hen house with the monitor very close to the top of the tin roof if sounded just like something was tearing the roof off the hen house. Mr. Roo usually starts with his crowing the earliest it was 3:29 am and that's when the monitor beside my bed goes click.
