Hello, duck sick.. 1 of my 2 yr old ducks got sick after freeranging with 4 month old chickens. Her symptoms are weight loss, lethargy, staying to herself. Very little drinking and not eating much. Isolated her 3 days ago first day I gave her warming medicine she only ate a few peas and would drink a little. second day she wasn’t better so hears it might be cocci, so I changed out her water and gave her water with Corid. She will still drink a little. third day still not eating could it possibly be anything else? And now it seems I have a second duck that’s looking the same. Thanks for any help.
