I do what Jo Ann does, and take out the biggest kit, leaving the smaller/s to nurse from Mom.
I keep a feel on their tummies through out the day.If all bellies are round full, and warm for the most part I don't try to hand feed.
If one seems not as full, take the fullest one out and put him with Dad for a while.An hour or so won't hurt.
I have to tell you this one,
my very first litter from my very first pair, got left in with Dad for a whole night when they were just 3 days old.Yes I mixed up Mom and Dad :blush2:and put the babies in with the wrong parent. First thing next morning I looked in the cage thinking hmmmm Teasers droppings are some small, looks just like Pokies' :doh:they were pokie's.
Mom was some glad to get the kits back, but Dad did just fine keeping them warm.
I've always wondered how long did they try to nurse from him before they gave up.
I still have them all.
