So sad to have to let the goats go, I'm considering rehoming some young ones who aren't suited to their current home for similar reasons.
My neighbours have in the past phoned me to say there's a problem with the goats (and sheep/lambs but that's another story, they don't keep livestock and don't really get it!) - I was in the pub so not best pleased to have to come home. They were indeed shrieking as they can do, it was late and we live in a valley so noise travels. It turned out the goats had been evicted from their stable by escaped piglets who were trashing their home - the goats were standing in the pig stable doorway just crying!
Same neighbour also told me that a passer by had stopped our opposite neighbour to say they thought someone was hurt or crying - luckily this neighbour has had goats and was very sensible and said it was genuinely them and nothing to worry about - passer by took some convincing apparently.
On the whole everyone has been very understanding and helpful, no complaints about noise or smells or escapees, just genuine concern - we live by a busy main road. It does make me think we need some signage and phone numbers for people to contact me on, got a public footpath running alongside one field - possible marketing opportunity being missed too!
