I have a hen about 4 or 5 yrs old and she was out in a thunder storm. She and another hen would not walk after the storm. One hen is fine and the other will not walk. This happened about a month ago. She layed a couple of eggs. I keep her in a basket and let her out everyday in the grass, give her feed and water and she tries to get up using her wings but her legs won't work. When we hold her she will push on our hand with her feet. Anyone else have or had this problem?
