My chicken is about 4 years old she's a barred Plymouth rock and in generally good health. The day before yesterday she swallowed a pieces of glass, I slit her crop open and removed all the pieces of glass or so I thought. Right now she's fine but I can still feel a few pieces of glass in her crop most of them are small but one is larger it's not as long as the piece I removed but, I worried should I go back in later and remove it or give her some granite grit and let it grind down? I'm worried that it might puncture her lining, but I've been reading the Internet and a lot of websites seem to think that they will either grind it down or it will stay inside but not cause any harm. Opinions?, suggestions?, similar experiences? all will be appreciated!! Also second when I cut her open the cuts were made vertically one on top of the other and I closed the crop hole with a little crazy glue, because I didn't have any suitable thread at the time ( Yes, I know Crazy glue, but doctors use a very similar product in human called dermabond, I'm a nursing student) anyway the crop layer is closed but I didn't close the very top layer of skin [the one that is like a thin film] is this a problem? The crop and top layer of skin appeared to have adhered together is this very bad? what are the possible complications? Do I really need to separate the layer by re-cutting to separate them if they have adhered? how would I do that?? Thanks any help would be really appreciated!!!!!! p.s if anyone is wondering she's doing fine, it's 2 days post no signs of infection, doesn't seem to be in pain, appetite is great even though I'm keeping her on about 6 very small meals a day.
