I am raising 2 (boy and girl) young (approximately 2-3wks old) grays, and have been for a week now. They are kept in the same conditions, fed the same diet (esbilac milk replacer with probiotics) and occasional pedialyte (diluted).
They both took to the 1cc syringe very well and both have both regular bowel and bladder movements. Initially, both took approximately 3/4 - 1 cc. The boy was easier to feed, the girl liked to root around a bit before eating. The boy always seemed to pass out after eating (to which I assumed was a satisfied belly), the girl likes to squirm and crawl before settling down. We initially tried to feed every 2hrs or so (even through the night if they wanted) but have stretched the feedings to a little less frequently.
We keep in a box with a non-shutoff heating pad underneath, and a heater to keep the room toasty.
The last several days, the girl has increased her volume intake, while the little boy takes the same, or possibly a bit less. He also is not as eager to take the feedings. Once he does eat, he'll curl up in my palm and go to sleep.
It now appears the little girl is beginning to outpace the boy in size, but not significantly. But with the more robust appetite and the appearance of getting a bit bigger, I worry that something might be wrong and want to stay on top of things.
He is not bloated. They both stool similarly. I assume that one might get a growth spurt and this could account for difference. But my concern is that I am missing something and any help/advice would be appreciated.
There is no squirrel rehabilitation nearby.
Additional info: very young. Ears starting to separate. Stool became 'yellow' with the formula. They both will 'crawl around' and grunt. No abnormal respiratory sounds. No scale to obtain weight.
Thank you,
Joe
