I noticed my 16 week old chick was limping for a few days so I brought her inside. She seems fine (other than the limp) She has a good appetite and has some good energy. I am keeping her in a small crate and providing food with additional vitimins and ACV water. I noticed a few mites but they went away with an application of Adams and Ivermectin. She must have been pale and under fed because her color and stools are better today. It seems like her leg is paralized - Its smaller than the other leg like its atrophied, but other than that it seems fine. It doesnt seem painful to her when I palpitate it and there are no obvious bruises or broken bones. I did notice a large red bump (pictured) on her body near the hip socket. What could it be? Would a spider bite cause these symptoms? Could it be Mereks? I have not noticed an improvement in the limp with the additional vitamins so I dont think it was vitamin deficiency. I feel like this red bump is a clue but I dont know what it is. There are no other red bumps on her body. Any help is appreciated.
