i rescued a sick silkie chicken, she is sneezing, has an heavy breathing and also one of her eyes is puffy with white bubbles. she eats and drinks in an okay amont (she has a small appetite) and she is only active around people as she follows them. i started gaving her the medicine 6 days ago (once a day) and there is'nt any improvements to her syptoms. her nose is clean, her tempatore feels fine and her throut does'nt have any thing strange in it. what should i do ?
