Just a rant really, I know I’m not being at all unreasonable. We live in a very rural area that is somewhere people like to visit. It’s pretty and remote and lovely. The only house within about a mile or more is a holiday let. Owners are lovely and actually bought the property back that their grandparents used to own 60 years ago. We have no issues with them. We also have no issues with 95% of their guests. They are usually very quiet and respectful and all that.
We had a family arrive yesterday for the week, with a 5 & 10 year old (we have a 4 & 9 year old, so great we thought!). They came over to play yesterday afternoon, fine.
I woke up this morning to their 5 year old in our lounge (we have like 5 doors, it’s a big old farmhouse, we don’t lock them usually at night as literally no one bothers us down here). I returned him to his family. 
They attempted to come over several times today but I sent them back as we were having an Easter egg hunt in the garden and also having lunch. They finally came over again in the afternoon (I was in the house tidying up after lunch). We live on a farm so I can’t really see much from the kitchen, or else if I’d seen them, I would have intervened.
The 5 year old got into our chicken pen, let all the chickens out, threw about £5 worth of food and grit everywhere, and then appeared in my lounge (I was tidying up toys) and chucked 4 eggs on the floor (thankfully didn’t break!). I’m over it.
I only discovered the chickens let out (for foxes to eat) and food thrown everywhere just now as I went to tidy up outside for the evening. I went to knock on holiday let’s door but was dark inside downstairs and I could hear kids in bathroom upstairs so they are obviously doing bath and bedtime now.
I’ll speak with them tomorrow, but I just needed to rant. We’ve had so many people traveling to our lovely part of the country the past couple years and it does provide income for many local people (not Dh and I, we work in careers totally unrelated to tourism). But these are the first CF we’ve had in a long time and it just irritates me. Every time I’ve returned their children to them, they’ve just been in the kitchen, drinking, and oblivious. We had a bonfire burning today. We have a river with deep fast flowing water. We also had our puppy out this afternoon, who is lovely but very big and jumpy, which is why we are careful to only have her off lead on our own farm. She definitely could have injured one on these kids in excitement if we hadn’t known they were wondering around our land. And also just the damage and expense to our livestock. I’ve had to clean out the duck and chicken houses because they filled them with pellets and they can choke without access to water. They’re here 5 more days! I will go have a word in the morning, but in the meantime, just arghhhh!
