Have rehabbed several gray squirrels. Just received our first flying squirrel. It has fur all over and on belly, eyes open, weighs 17 grams, feels very bony, clicking sometimes when it breaths. Have a 1ml syringe, has taken 2 feedings of pedialyte. Can it eat 20/50 fox valley squirrel milk? If so, how much per feeding? Is it old enough for solids yet? And I’m thinking it needs an antibiotic due to the clicking (possible pneumonia). What antibiotics are good?, dose age?, administer in milk?.
