I have a Rhode Island Red chick who isn't doing great at all. She was fine for the first 2-3days when I brought the chicks home. 2nights ago she ant the other Rhode Island Red chic started acting lethargic, and having pasty butt, and liquid poop. I gave them corid yesterday but after talking with some other people on byc and seeing one chick get slightly better but the other get worse I decided to try giving them sugar water and went to the store for nutri-drench. Non of my other chicks have showed any symptoms and are acting fine. The smaller weaker (RIR) has just been losing more and more energy, I gave her the nutri-drench but it didn't really do much for her. She doesn't want to eat or drink much, and is having a hard time walking. She just lays in the corner. I've moved her out from the brooder with the rest because they were trampling every where and I was worried they would injure her or squish her. Idk if there is anything else I can do fr her but if so I want to know. Thanks in advance for any advice She opens her eyes and lifts her head on occasion. I'm really worried about her, especially because she's so young.
