I acquired my yearling male Black and White about three months ago. He got settled in and was eating regularly, but now doesn't seem to have interest in any food offered. I have provided him a hide with a deep layer of hay and leaves which he used for about 3 weeks. I figured he was down for the count. About a week ago he came back out. Still no food interest, but he took a bath in his water basin. Everyday he's sleeping in a different spot. He seems pretty sleepy. Just not in his hide. I have reduced the lights day length, but don't want shut them down completely because he's still awake. What should I do? A little help would be great.
