2nd sick (lethargic) hen after introducing new ones

All at once? For the healthy ones too?

I would treat the sick one with those I mentioned, but only worm the normal acting birds. Keep an eye on

Update: She is barely alive. She hasn't eaten since Friday morning and she won't drink; I get a little in her beak with a syringe. I have given her Wazine and tetracycline hydrochloride as well as Sav-a-Chick (vitamins/electrolytes). I gave the active chickens Wazine yesterday and will give them Valbazen in a week when it arrives (had to order it). I'm just hoping now that I don't lose the remaining three.
