You have mother and she feeds other ones so there is no point in using replacements if she's healthy and have enough milk, just try to feed the wrinkled one keeping it close to her nipples. If you worry if she has enough milk make sure she drinks lots of water and has unlimited pellets, also give her some rolled oats. Those replacements are for if you don't have mother or any other chance to get natural milk so I wouldn't start with them unless there is absolutely no other option.i would like to try hand feeding. i cant seem to find a local place that sells milk replacer for bunnies. would kitten (for cats) milk replacer work?
oh no! what is the most likely cause? i dont think they are too hot. the basement that they are in is on the chilly side even with the radiator i have going on full blast for them. so maybe they're too cold? how can i get them warmer? but it just may be that they are hungry. they do look a little thin to me. but it was only one kit making that sound...That squeaking sound usually means they are too hot or too cold.
If they are the correct temperature, it could mean starvation.
