I have a NZW this is the third litter she had the first one all 8 died the second 7 out of 8 lived. Now this is her third litter she gave birth this morning to 9 but in a few hours they was all cold and about to die. I warmed them up in the house but still lost 4 of them. But this whole time she has not pulled any hair from her neck and it is bulging with hair. We have her in the house in a smaller cage with them hopping she will feed them and keep them alive this time. any one have suggestions? any help would be nice.
