ok thanks. do you think that the doe has nursed them at all? after all, they have survived this long until i started hand feeding them...
Of course she feeds them, you started this thread Friday and they would have no chance to survive that long without her feeding them. I personally don't see need to use replacements at all, what I meant by hand feeding was that you could try bringing them to their mothers belly a couple times a day to be sure and give them an extra chance, as in video I posted.
I had some weaker wrinkled kits and because others were stronger they had no chance to get their portion so I used this hand feeding and also removed fattest kits from nest for one-two feedings but that was just first few days after that they were strong enough, also if there's more than 6 kits or if mother looks exhausted sometimes I split kits and make sure weakest ones are warm and fed and get more milk than the fat ones. But I always take a very good care of mother she needs to be well fed, happy and relaxed and she will take care of her babies.
In your case you have mother and she feeds them generally, you just need to make sure she has everything to produce enough milk, maybe stimulate her by bringing kits to her belly, give additionally rolled oats, herbs etc, and she'll do the rest.
Your mother looks strong girl not skinny and all, she can do it herself.
In your photo actually was very hard to see bellies but honestly they didn't look that much wrinkled. Maybe you could post some new photo so we can see their bellies?
Good luck anyways please don't separate them from their mother.
