I need help weaning my 6 week old Flying Squirrel. He seems completely healthy, energetic, and he absolutely demolishes any formula I give him. However, even after 2 weeks of continuously introducing him to rodent block (Henry's HB, to be specific) and leaving it in his cage overnight, he has shown zero interest in it whatsoever. In addition, he shows no interest in any vegetables or other solid foods I offer him (I've tried Romaine lettuce and small cut Radish slices). I'm wondering if I've been giving him too much formula (for perspective he weighs about 40g and I give him 2.5ml of FV 20/50 every 4 hours). Any advice or weaning techniques would be appreciated, as I'm a first to all of this. His nest was knocked out of a tree when he was barely 1 week old, and I've been taking care of him since. Thank you.
