Hello ,
I would have to disagree slightly on this one . I have worked on many farms with sheep over the last 30 years and ,although I am by no means an expert, I have come across more than one or two sheep ,both with and without horns , that hadn't been mistreated in any way but , were downright dangerous. It was mainly rams , all they are doing is protecting their girls in their eyes. But on more than one occasion they have knocked me off my feet. Like goats it just depends on their temperament, mainly good but now and then a nasty one . There is a ram on the next farm to me here , he will chase you all over the field to have a go , and he can really motor. He has no horns to grab hold of either, so you either hope you can out run him ,or don't go in there with him ....I choose the latter !!! Ewes with young can be very dangerous too, if you aren't used to them . Once again that is with or without horns. The main thing is to take care with any sheep till you are used to them and they are used to you ....
cheers
