Question Author
That's very helpful. I'd never have thought of the worming question , Lankeela, ( what would we do without you on dogs and horses?).
Giving the old horse a companion would be an idea, because he lost his companion, a Suffolk Punch, last year.Not sure that a donkey is perfect, considering the braying. Do they normally bray at night?, I may give it a try, as a favour, subject to it being removed if anyone complains. (Anyway,it belongs to the wife of the local publican.She could always answer by refusing to serve any complainers LOL That would make the local paper! )
