Ethel, my Silver Laced Wyandotte, seems to have been eating mud or dirt, and getting her beak all clogged up. It has been happening for at least a two days, possibly longer. She keeps getting a whole lot of mud all caked in the point of her beak, both the upper and lower parts. It looks like it's stopping her from being able to eat properly, because she keeps pecking at food but doesn't seem to be able to swallow it - possibly because the mud is blocking her tongue. A couple of times now I have dug the mud out, but then an hour or so later her beak is all full of mud again. I think she's losing weight, and she's acting unwell (standing around away from the others, closing her eyes and puffing up her feathers). I'm not sure if she's unwell because she can't eat properly, or if her being sick is what's causing her to eat the mud. Any ideas about what it might be and what I should do about it? I'm getting quite concerned about her. As an aside, she also scratched her eye a few days ago. Not sure if there's any relationship between the two events (wondering if she is eating mud by accident because her depth perception is messed up and she keeps missing her food).
