I have a seven week-old Brown Leghorn with the following attributes/symptoms: * skinny--she's much smaller than my RIR, Black Star and Golden Comet, although the same age * has a "bony" chest--I thought this was just her breed, but now after reading more think it might be bound or impacted crop * has been "convulsing" like she has hiccups or needs to vomit (mainly at night, I don't see this during the day) They've been outside the past two weeks eating bugs, worms, and grasses from the yard and garden, but I have been feeding them their chick starter as well. I added grit a few weeks back, but they don't seem to eat it. I'm worried that I may have put this little one in danger, by not doing something sooner! I noticed it the other night, but while she was readjusting her feet underneath her--and I honestly thought it was just her bony-ness. Per other posts, it seems other symptoms are inability to defecate, minimal feeding and isolationism. She defecates just fine--normal, solid poo and she eats with the rest, albeit not as much. She's not a total loner, she sometimes does her own thing, but just as often she's running around with her Black Star buddy. Some of the symptoms/behaviors seem to implicate an impacted crop, but not all. What can I do--just in case she has it?? I read on another post olive oil soaked bread? Can I give this to all of them? I don't feel I need to separate her from the rest as her "best friend" cries incessantly until they're side by side. In regards to food. I've been giving them feed in their cage and sprinkling some in the garden. Although one area where I spread feed in the garden is the same area that gets wet from watering over-spray. Could it be food that is/was wet and spoiled??? I'd love some advice! I had chickens growing up and either 1) they never had these problems or 2) they did and survived them. Maybe it's the mom in me coming out, but these are my little babies and I feel wholly responsible for their little lives and well-being! Thank you in advance!
