I noticed that Flo (our new Alpine/LaMancha bottle doeling) was eating dirt today. Not just pushing it around or nibbling, but eating mouthfuls. Does she have a vitamin deficiency?
If she is eating dirt, she'll likely also eat minerals. Put them in your hand at first.
She may be trying to populate her gut with good bacteria, too. A lot of baby herbivores eat dirt by the mouthful around the time they start eating solid foods. If she insists on it, you may want to be sure she has access to "clean dirt," like from the woods or from the garden (if you don't use chemicals or fertilizers.)
Can you include some raw goat's milk in her bottle? That might be helpful, too, as it will have good beasties in it.
Baby horses stuff their faces with their mama's fresh poo.....really stuff their faces! Huge mouthfuls! Is that why they are called road apples or meadow muffins??? But it is to populate the gut. Probios or yogurt sounds far nicer....keeps 'em more smoochable, too.
She has access to some goat pellet and I put out some loose mineral where she can get to it today. Other than that, she seems happy and healthy. Thanks for the ideas, everybody.
