Welcome Blusam. There are a lot of nice guys on this forum that have tons of information about taking coyotes over bait. We all love photos, so be sure to post yours as well, and tell how you go about it.
This summer I am continuing to put bait out though I am not shooting them this time of year. I can legally shoot them year 'round but just choose to wait until the fall and winter months. I've had some activity at the bait recently, one is definitely a female that I suspect has pups.
Here are a few trail camera photos extracted from video. I have my cameras set to video, seems I get more of an idea of what's on the bait by using video.
The coyote knows the lights are up there. Seems she always looks up
at them, even though they aren't turned on.
This one came during the day, very unusual. Time was abound 1:00 PM.
As to a barrel for dog food, DoubleUp may have some ideas on that one. There is one idea,
however that might work, and that is to use PVC such as in the photo below. DoubleUp
and I talked about this as a potential dog food dispenser. I got the idea off YouTube and
use it as a corn feeder. I initially cut the hole too large for corn, 1.5", and then redid it
with a 1" hole. I think for dog food you might want larger than a 1" hole, but might have
to experiment a little. I have added a cap to the top that keeps the water out. Just a thought.
