I have a young Muscovy hen (first winter) that is walking around like she has no neck, with her head tucked real low and walking upright. I also noticed she is not eating any of the corn I have been throwing them as a treat. All of the others are going crazy over it and she just sits there. I put up all the rest for the night and tried giving her some alone and she acted like she couldn't reach it or something, just kinda put her bill down towards it and walked away real slowly. Could she be sick? She doesn't look thin or anything, looks healthy other than her strange behavior. Could it be she is getting plenty of bugs (in this weather?)? I figured she would be hungry and that's why I am giving more treats than usual. It's been very cold.
