They've been in most of the day, 3 water chages today, as it involves going down to the field well it's getting a bit frustrating!
I was thinking of making a hole in the front of the pen and hanging the bucket on the outside, but it seems just hanging it high-ish on the wall seems the way to go, thanks all.
The bucket rings seems a bit dear, counting in delivery (can't find any locally), so OH is conveniently doing a job for a metal fabricator,
I'm thinking of a strip of metal bent semi round with flat bits to bolt to wall. sound OK?
