Our doe Iris cracked her horn today. Checked her this morning and she was fine. This evening she has blood all over her face and a cracked horn. We applied blood stop powder even though it was not pouring blood. Then we washed off the horn/ her face with clean water so we could see the crack better. It doesn't go all the way to the bottom of her horn. We put iodine on it and she is back with the herd now. She is acting normal. The weird thing is that she is the only one who has ever broken a horn. She broke a piece off the top of the other one months ago (we never saw any blood just noticed a piece was gone). This time it is cracked in the middle. Any advice?
