I have the strangest calves. I bought these 2 Angus/Holstein calves from a dairy farmer. They were raised in a dark barn with very little lighting for the first week or two of their lives. They are now about 12 weeks old. They were bottle babies and seem to have gotten skittish since they were weaned. I have them set up in a shelter with a couple of doors ( which lets in some sun facing south) They will not come out at all during the day - I have to make them go out and they just run back in! I do see them come out when the sun is setting in the evening. I have tried to move their hay out so they will go out and eat grass but they stay in and just eat their grain instead. I think they are out quite a bit at night but I don't know for sure. Is this healthy? Should I just take down a side I have made with canvas to get them more used to the daylight? I have had lots of calves but not like these two hermits! I really would like to put them with the rest of my herd but I know they would be bullied and it is too far away from the grain they need. Has anybody had nocturnal calves before? Any great ideas? I would think they would be healthier outside in the sunshine and eating grass.
