I see he is a baby and you have had him for a month. Have you tried hand feeding him? You could also put your finger in front of his feet and hopefully he will step on. You could put a stick in front of his feet for him to step on. Good luck.
Mine did the same and is about the same age, I started leaving my hand an.inch away for like 10 mins I'd stay there to let her know I mean no harm then lil by lil was able.to.pet her then I would hand feed after all that , so she knows thaats the hand that feeds her lol,,, and now she climbs right up to me try doing that everyday for awhile
