Hi, my 2 year old mini rex just delivered 6 babies last night, one was still born. (August 6th around 11). and i noticed today her nipples are red at the tips like her babies are sucking too hard because they can't get anything. i saw her go in and feed around 1 pm for a couple minutes and when she came out she flinched when i touched a nipple and her babies were sucking and digging at the blanket she dragged into the nest. it seemed like they were still hungry.
