My birds all free range. They put themselves in at night. Late last week I noticed one of my pullets laying in some hay in the horse paddock. I just thought "I need to remember to get that egg." But there was no egg and no pullet later. Next day she was laying in hay about 300' away near the goats. I thought "she's practicing." At chore time...no egg..no pullet. I never thought anything was odd about it. The next day it was rainy and she was sitting in the horse paddock in mud. I went in and picked her up and her legs just hung there lifeless. She's a big girl and looked perfectly okay. So I thought, "poor thing got stepped on or something? No sign of injury though. Probably will not make it, but not in any apparent pain." I tucked her into a ground level laying box and covered her back with a blanket, gave her food and water. It's been a week of lifting her up and trying to get her legs under her. She lays with them out behind her. I thought she'd be gone, but perhaps she doesn't have the internal injuries I suspected. Her legs are normal/warm not hot or cold. Tonight she was out of her nest box about 6' across the coop. She must drag herself with her wings...? She eats and drinks.... I'm lost. Any suggestions?
