Limping & Dragging her wing.

[sepaditty1]

I had to put my little Polish hen out of her misery. What started as a slight limp quickly took her down.

I feel awful for it?, but I'm worried about the others. She was limping and dragging on the right side. What happened? What was this? Are the rest OK?

It could possibly have been Mareks disease. Botulism can also cause paralysis, but it should affect both legs, and can spread up to the neck and head and breathing muscles. Here are some links to read about Mareks:
