We recently bought a beautiful blue roan Hancock mare. When we were looking at her, she had a lot of orange on her tips (mostly face and her mane/tail), but after two weeks of being here at her new home, she seems to have lost a good bit of the orange and is becoming darker.
Note that her diet has changed from 24/7 very short grass to 24/7 mountain grass with a lot of clover. We cut her back to about 8hr of grazing now as she was getting hot on all this sugar.
Before, at her old farm ^
Last week, after having a decent roll in the round pen ^
ETA: Duh, my question! -- Do you notice a change? If so, what could be causing this? She gets no grain and no hay, just grass.
