So two weeks ago, I ended up having to put my dwarf rooster down. I never actually figured out what he had but it was an awful sight to see. After some research, it seemed a lot like Newcastle's Disease with his last few days. The weird thing is that my two other hens are perfectly fine (as far as I can tell.) So. One of my hens had this horrible, horrible smell when I bought her. At first I thought it was because of where I got her. It's literally been two months and she still has this foul smell -she's active and eating. Although I have noticed her growth is severely stunted... (I can't help but find her extremely cute but I'm really concerned -she's the size of a twelve week-old hen.) All three of my chickens didn't respond to the Duramycin10 I was giving them... So my question -what medicine should I try now? Online and from previous responses, Coryza or MG were the only disease I found that had stunted growth and smelly symptoms. (Those are the only two symptoms she has -the other shows none which makes me think she's also a carrier.) This smell NEEDS to go away! Also, what's the difference between MG and Coryza..? I'm new to this, sorry. Last -how would I go about getting more chickens if I ever wanted to? Or if I even can? Despite the circumstances, I'll keep them anyway. They're more of pets than anything. Thanks!
