Hi all, I'm new to chicks, and could use some help. We got 3 day-old chicks almost 3 weeks ago. About 10 days ago, one (Jane) started to seem sick and weak. She first wouldn't stand up, and since then lays down sideways. I don't think it's straddle leg, and i'm not sure what to do. We are thinking of putting her out of her misery soon. She moves around by pushing herself forward on her chest, and will eat and drink. However, she's now so much smaller than the other 2, and they will eat any food put in front of her, and step on her, etc. She peeps alot. Her poo is mainly normal, maybe a little runny. I've been giving her poly-vi-sol (no iron) and eggs, and all the chicks seem to really like nutritional yeast sprinkled on whatever they eat. She's skin & bones, her fluff & feathers are un-preened, and she seems miserable. Any suggestions? Is she heal-able?
