Great question and one that isnt asked often enough!
I feed pinky mice to newborn Eastern Indigos that will accept
them, both scented and unscented.Pinkes get fed live, not
frozen/thawed.
I switch them to rat pups as soon as they are large enough to
comfortably swallow them. Rat pups lack the calcium of an rat
with hair,however, so I try to switch them to rat chubs with
eyes open and hair. I get better growth on these than the rat
pups.
My adult Easterns almost always consume exclusively RATS, from
small to LARGE(For large Eastern Males out of breeding season)
When supplies have gotten thin,I have resorted to using mice
on adult easterns, say about 8 each. This is NOT my preferred
method, rats are the best choice imo.
I supplement all my Eastern Indigos diet with the following:
Quail, Chicks, Smelt.(And it REALLY Smelt after this too!)
I feed only freshly pre-killed or frozen/thawed rodents and
chicks.
Deans right, better growth comes from rats, mice are like
Angora rabbits, ALL FUR and no substance.Remind me of crickets
Hope this helped
Sincerely,
