I have a chick who hatched last nigh with what I believe to be a slipped Achilles tendon. I've found some posts and a poultry site on how to treat, but I need clarification. What exactly should it feel like? I've felt her joint, but it just feels bony. Do I need to extend her leg all the way back to put the tendon in place? She doesn't like it when I try to move her leg back. Does anyone have any experience with this? I could really use some help!
