I was born in the country and I have seen all kinds of animals born, the color mixture is very normal, what is not normal is that they are born two days later, although I was only 14 years in the field I never saw I heard of late cases that were born alive, I have seen if they were expelled after some poor accommodation of the animal, but I always saw dead, because they are passed from the period of parturition.It is for a consultation to the vet wikipedia.
This is one more reason to celebrate my friend.@papa-pepper
Excelling news, the family grows. Congratulations
