I lost a hen 2 weeks ago. The night before she died I noticed she was walking slow and looked a little awkward. The next morning she was dead outside the coop. Her sister is almost exactly like her in appearance but a little bigger in size and was displaying the same slow awkward walk tonight. They are Olde English bantam / B. Brahma cross. They both seem(ed) like they were laying eggs fine but I'm wondering if this is a sign of being egg bound? If not has anyone else had an experience like this?
