A few weeks ago I noticed my older girl limping/ leaning to one side, I made sure she was alright and assumed it was a Pulled muscle as she is older. Well about 4 days ago she started walking like this, I separated her, and figured it was probably from a selenium and vitamin E deficiency so I have been giving her that. I haven’t noticed any changes though and am wondering if anyone knows what this could be signs of? I got her and her sisters about a month ago and she is assumed to be the oldest, I am feeding them the same as what they’ve always been on and doing nothing different. I do have three Drakes that did get aggressive but they are separated from her.
