please help. I have a broody with one week old chicks. I just moved her outside to a pen so that she could walk around with her chicks. I noticed that she hobbles on her hocks and cannot stand on her feet. I have treated her with Ivermectin and put electrolytes in her water. I also crushed a Vit B tablet into her scrambled egg with a squirt of vit D. PLEASE!! Any advice or help. She has chicks to raise.
