I have some quail (four of them) who stand still and close their eyes for a few seconds. The females who close their eyes still eat a lot, and are chubby. The one male who has it doesn't eat as much (they never do), but I have one who seems more unwell than the rest. He would just go over to the darker area of the cage in the corner and close his eyes whilst standing up, which is exactly what my female Pepper did before she died. His poop seems normal, except it's not a lot. It was a small amount, compared to the foam excreted on top of it. He seems as if he doesn't eat a lot as his crop felt completely empty, but I'm not sure if it's empty because he doesn't want to eat, or because the other males keep annoying him and preventing him from eating.I separated him and gave him some canary seed mix, he ate quite a bit and I could feel some of the seeds in his crop, but after eating a small amount, he lay down and closed his eyes right next to the food dish. It feels as if he has lost weight, as he's 20 grams lighter than his brother. So is it a sign of worms (and should I go buy a wormer) or is it just something else? I just want to be sure because I don't want to lose anyone, and the symptons are among another three as well. Thanks.
