We have saved a family of 3 greys from a fallen tree. The momma was killed. 2 boys and a girl grey squirrels. Currently 7/8 weeks old. Was curious how often should they be fed when weaning? We were doing 5 hour intervals of formula but my big man is starting to refuse formula.they have water and all 3 are seperated. (We had nursing issues.) do we keep feeding the healthy diet every 5 hours? They are all getting Henry’s squirrel blocks.
