rescue bun had litter july 5th

I rescued 2 rabbits june 15th. They were living in a 2ft square of space each outside,no food or water. Person didnt even know what sex they were. I ended up bringing the girl and boy home and had to leave the third as i had no extra space. July 5th i get the surprise of a litter of 6 little ones. I have had 2 litters in the past so knew what to expect and how to handle it. What i am confused on is these babies from minutes after being born have appeared to have some hair. Normally kits feel rubbery,these have never felt that way,they feel silky. Their bodies have a sheen to them. Could she possibly have held onto the pregnancy longer due to the stress of being rehomed? Checking them daily and they are all lively,doing very well.

That isn't out of the normal, imo it's just light coloured kits that look pink. Doesn't look any different to what I'm used to..

they do look normal, sometimes some of the babies have skin that does have a sheen, for me it is the fatter ones that have the sheen, but they look quite normal.
