Our baby NW are 28 days old today. We have 5 really good eaters. Those are getting big and their patterns are really starting to emerge. The other 3 still have not eaten. I'm beginning to worry about them. They look so thin and tiny compared to there eating siblings. I've offered worm, pinkie, egg, and salmon. Does anyone have any thoughts on this. It also seems odd that the ones that aren't eating are the only 3 that were born with very dark and defined markings. Am I being concerned too soon? Is there something else I could be doing? They all eat in their enclosure. I've tried removing the 5 that eat and putting mom in, but that didn't work.
