very worried about 2 week old kitten

my cats 2 kittens seems so tiny compared to his brother and sisters they are all chunky weighing  in at 8oz  but the small ginger 1 and the small black and white 1 only weight in at 7.15oz and 7oz i wasnt sure if i should feed them a bit myself just to make sure they are having enough 

How is their raise day for day? Does it go 0,4OZ or better daily?  If yes, it should do. Although give the exact numbers - and keep one extra eye on them.

Besides, if the others are 8 OZ and the smallest 7, it is not so big difference, really.  That numbers are not worrying me. Nor them being thus somewhat smaller.

But, if you yourself notice they are visibly weaker - or in visibly worse shape - it could be good reason to give them some extra.

Can you get goat milk? Best raw milk, but bottled or frozen are ok too.

If you do have a good kmr you can of course use it too.  

Good luck!

I basically agree with StefanZ.  I would not be worried AT ALL about the difference in weight as long as the smaller ones are gaining.  .3 or .4 ounces a day would be an absolute minimum that they should be gaining, but as long as they are all is well.  (also do not panic if one day one kitten does not gain or even loses .1 or .2 ounce- this happens- but if it happens 2 days in a row that is very bad and requires immediate action).  

In your case, this is actually a pretty small difference in weight- I've had litters where the difference was much bigger and everyone still ended up okay.  Jut make sure they all keep gaining.  Also you may be surprised and the smaller ones may catch up and get bigger than the bigger ones!

Thanks for being concerned about your kitties

Just to let u know I took the kittens and mammy cat jess to the vets today for a check up and he said their weight is all ok and they are all in good health he give me a wormer syrup for kittens but said no need to flea them coz none of them have any fleas which was good to hear,
