I had something similar happen last year with Mama beef cattle and their spring babies!
It took my brain a while to understand that there were a bunch of COWS in my garden! But when that clicked in, I called the neighbor that owned them and he was none too pleased, but took care of it right away.
Not much damage, but a lot of cow pies to toss into the compost - so not totally A Bad Thing, LOL!
Years ago ... well, decades ago, I had just gotten up on a Saturday morning. When I looked out the kitchen window, the horses were galloping like idiots, tails straight up in the air (look like flags)! I went out on the deck to see what I could see ... heard ‘mooing’ and a herd of cows was coming down the old roadbed on the other side of our fence - across the yard from the horse pasture. I threw on some decent clothes (shorts/T-shirt) and ran down the driveway to close the gate at our entrance - did not want the cows coming up in the yard, possibly falling through the septic tank (old one that needed replacing).
Since I knew who the owner was, I ran back inside and called - woke him up. He asked if I would please try to keep the cows out of the road until he could get there - I told him I would try. Ran back down the driveway, got through the gate & started shooing cows off the road. A neighbor across the street came out on his deck - he’d thrown on a pair of shorts and was barefooted, did not want to get involved with the cows, but he was watching & calling “encouragement” to me.
So one large cow was in the road - a car came and I waved them down, they slowly made their way around the cow. I tried shooing “it” out of the road, but it was the herd bull ... somehow, I had not noticed. He put his head down and started snorting and pawing ... ruh roh!! I took cover behind a large bush just off the road, at which point the neighbor was almost rolling on the floor of his deck laughing - I have been chased by bulls before (at my grandparent’s farm) and I didn’t think it was funny at all!!
Once I was behind the bush & no longer flapping my arms at him, the bull lightened up a bit, but he wasn’t moving. About that time, the neighbor pulled up - his wife was driving, he was in a bathrobe, and he had his ‘herding stick’. The cows knew him and he started herding them down the road, back to what ended up being a break in the fence. This guy could herd anything - he had helped herd two very large (400 lbs +), stinky hogs that escaped from an elderly neighbor behind us. The hogs got into the subdivision that is off our road and were rooting through landscaping. Animal Control was called - they tried ‘herding’ the hogs by flashing their lights & whooping their siren ... not very successful. Somebody thought to call the ‘herding whisperer’ ... he had his stick and very quickly had the hogs going down the road, back to the old man’s place.
We do have a large pile of horse poop at the lower entrance, near a pot of my mom’s fall flowers. She is NOT happy. I guess I’ll go clean it up & add it to my compost pile.
