Matilda has a terrible rattle in her lungs for quite a while. At times her nostrils get "buggers" and she has to breath from her mouth and I take a q-tip with oil and wipe them clean. She is a good eater and still the top hen. She is crippled from a fall two years ago and is slowing down b/c she is 8 years old now, but still gets around good. I've treated her with duramyin. Her eyes are clear and comb is still nice and red. Sometimes I wonder if its asthma? Any thoughts or any ideas, no matter how random would be appreciated! Thank you so much.
