Well I think they are stinking adorable! Before they became super popular I wanted them until I thought about the fox tails and other weeds that would infest them with stickers.
The only real issue at the moment is they are super popular which means very expensive and I’m not sure how long the fad will last. But if mainly for enjoyment that’s not a issue
If you do go with them or cattle of any kind know they are BIG, they weigh a lot and even being calm cattle you really can’t man handle them like with the goats. Usually one would want equipment to be able to give vaccines or doctor them if they need it. But I think if you get calf’s and halter break them and bond with them very well you could probably get away with not having the equipment and just have a halter and a small pen. So my vote is yes go for it and get calf’s lol
