I went out to the run this morning and one of my orpingtons was sitting funny and couldn't walk right. It was sitting on it's butt with it's feet sticking out in front of it. It can kind of hobble around a bit but would trip and the others were stepping on it and it didn't put up much of a fight when I picked it up. It's legs don't look broken but I'm no vet. This is a very young bird. Her sisters just started laying a few weeks ago. If anyone has any ideas please let me know. I Could really use some help.
