I need some help. I have a 3ish month peachick of unknown lineage who I'm 99.99% sure I bought already sick. I've had her for 5 days now and started force feeding yesterday. I've wormed her and started on Corid. Is there any way I could get her to put on more weight and eat enough by herself? She's deathly thin compared to my IB chick who's built like a brick house and weighs like one compared to her. He's only 2 1/2 months and smaller too. She gets around but is extremely lethargic and doesn't do much. Today is the worst I've seen her.
