One of my girls ears have gone a bit crunchy/dry looking. is this fungal? Iv just ordered some Super Souffle Cream from gorgeous guineas and am gonna ring the vets to see what they can do. What else should I do? Does she need seperating from her cage mate? is there anything I may have around the house I can put on her ears to help? It doesnt look terrible or sore and she doesnt seem in discomfort yet. but obviously Id like to nip it in the bud asap!
