It took forever for my feedstore to get some goat minerals in but they finally came in today. My only choice was the Purina ones so thats what I have. The bag said I could either feed it free choice or mix in a certain amount with their feed. I would like to feed free choice. Is there any chance of them over eating it at first? I gave some to the Lamanca and she started eating it without hesitation but would stop and do this kind of head and mouth thing kind of like a person might do if eating something sour the Nubian just nibbled a tiny bit and thats it. Anyway can they over eat it at first? Thanks.
