Ray, I'd like to add that if your plant is indeed a type of Elephant Ear - which can be a common name for Alocasia, Colocasia, Caladium and several other plants - most of them do have a dormant period at some point during the year. This is why they're generally used as feature plants outdoors in the summertime up north, and are taken in and let to go dormant in winter.
Animal manure is not generally used for indoor plants, because of the smell mainly but also because it's unknown how fast and how much the nutrients in it are released. You're much better off to choose a packaged, timed-release fertilizer. If your sheep manure released into the soil too quickly, all that urea in it could certainly burn the leaves of your plant.
If your plants are, indeed getting ready to go dormant, well you can't fight Mother Nature. We really REALLY do need to see pictures of your own plants to advise you better on this. We can then know exactly what type of "elephant ears" you have.
Also need to know your geographical location, please, so fill in your personal profile if you would. Air quality, humidity, how much light there will be through the winter, how cold does it get in your house at night, all are factors in growing plants indoors through the winter months.
