Hello i have a 4 month old speckled sussex hen. three weeks ago she started supporting herself when walking by using her wings. since then she will not use her legs at all (it has been about three weeks). I will pull on her legs and i can feel he pulling a little. Her toes are curled back all the time. I have put vitamins in her water and also put her in a sling for 3 to 5 hours a day. she eats and drink very well when i bring it to her. is there any thing i can do to help her? or is there anything i can look for that will help me give her a proper diagnosis?
