I have a goose sitting on a nest of eggs that are hatching, when I approach the nest they bark at me of course but one of the geese sounds like she has phloem in her lungs. Could this be because she has not been cleaning her nasal passages? Or does she have something that may be serious? It has been really warm here until today, tomorrow we are forecast for 6 inches of snow. Should I try to give antibiotics and if so what and where do I get them?
