I have one separated blue cochin that I thought was thin because she was picked on, she has been eating well in the garage but had runs, but she seems better now, but I was watching her today and she was opening and closing her mouth like she was crowing and thothing was coming out... weird?? she kept doing it, gonna run down and check her again.... she doesnt sneeze cough or sound congested, I see no worms in poop or in her throat... I will see if the ag close by has this sulmet, do u add to water? thanks!
