A few of my females are going through a heavy sudden molt. The one who has it the worst is walking very unsteadily, like she's intoxicated--sometimes sideways, sometimes backwards, sometimes normally, sometimes like she's dodging an invisible threat. It doesn't look like she's getting picked on. About two days ago, her back was largely bare, but yesterday it was mostly covered in growing feathers and more so today. There's also a large patch like that on one side of her throat. Is it possible she's walking like this because the incoming feathers are painful and she's trying to avoid the discomfort, or a nutritional deficiency from the hard molt? Or is she seriously ill? I've mixed Poultry Cell into the feed (28% protein) and plan to add NutriDrench to the water today.
