Cowgirl looks healthy enough. Calf is a sick little feller it appears
Calf is also part Brahma. Perhaps Santa Gertrudis breed. Better be on the lookout for his mama. They are very protective and down-right mean. It looks like south Texas country, home of that breed of cattle. Just a guess. I been nailed more than once by part Brahma/mama cows.
The cowgirl looks like she can really cowboy. Good lookin' ranch girl.
