I got home this afternoon and my silkie girl is acting really strange. She's all puffed up and just standing on my patio. She keeps turning her head to the side almost like she's falling asleep. I don't hear any rattling or wheezing, but her beak STINKS like something dead. I have tylan 50 injectable, but I don't know how to give a shot and am really not sure if she needs it. I put some yogurt down and all the other chickens ran to it as usual...she acted like it wasn't even there. I have some ACV but it's just the heinz kind not organic. I think I've read on here that I can put the tylan in water...is that true? If so, how much do I put? She's still outside but I'm gonna go get her and bring her in as soon as ya'll tell me what to do. Please help!!! She's my favorite and I really don't know what to do. The last time one of my silkies acted like this, I caught it to late and she died. I really don't want to lose this girl.
