thats all i could find on mice lol they have calcium its just not that much. i never had a problem feeding only pinks until they are big enough for the larger prey. they grew fine. they grew better than other diets ive used except rodents with every few feedings being fish with a multibitamin supplement that 50/50 calcium. when i raised a few babies on worms for 6 months they were significantlly smaller in size and muscle density. i dusted calcium every other feeding too. i also raised a few on just various types of fish with dusting calcium. a couple of the fish eaters devoloped problems and some even died within 6 months of the all fish diet. the only downside ive seen from feeding them pinkies and as they grow increase the size of the rodent was they would store extra fat and if not fed in moderation you can end up with a very fat and obese garter lol its one of those things where you gotta adjust until you find the right regimine that work for your garter.

i agree, they are very small for 3yrs old. my garters are that big at a month old. there is usually one runt in every litter sometimes more and sometimes there wont be one. it would depend on litter size. more babies more chances of deformed/runts.
