I have two three year old boars who don't do a lot. They're not scared of me, they're super bold when I have food they just hate being picked up or stroked. I've come to accept that, they're just antisocial guinea pigs. As much as I would prefer them to like me there's nothing I can do. They have a 152 X 60 cm double hutch with plenty of houses, hay racks, tunnels, trays, chew toys, food bowls yet all they do is sit in their enclosed bedding area all day. I worry about them not getting enough exercise or quality hay (since they wee on the hay they eat). Any short term + long term ideas on how to get them active and interactive?
