I agree completely. I left them with the housesitter last week, so I'm not sure if this one was always having an issue or just started after I got home. The housesitter isn't a chicken person, she wouldn't really know what to look for. Last time she was here when I had chicks, one died and she was devastated. I'm just glad it waited until I got home. Like I said before, I'm pretty sure it was the last one to hatch and it is what it is.It's sad. It is just part of it.Those sickly chicks that fail to thrive should be culled. You can nurse them along, baby them, give them all kinds of special attention...they usually die anyway. If they do live...they are never right, always sickly, poor immunity, undersized, not birds you want to breed from. I know it sounds harsh, its just more humane to cull them immediatly. The more you hatch, the quicker you will be able to identify the "fail to thrive" chicks.
