I have seen white and pied deer up close, I have noticed what look like very bright pink patches on their antlers. Do you believe those are the sunburn marks on the antlers? If so, I have seen the same marks on several all brown deer antlers. Or is your thought that their whole antler is constantly healing the sunburned parts, thus not able to put as much energy into growth? That is a very interesting theory. Do you recall the pied yearling from last year or the year prior that was at a ranch in TX who scored in the high 200's, I would be interested to see pictures of his antlers when they were in velvet. I remember that deer having lots of color variation, I cannot remember what his antlers looked like however.
