I posted on here not to long ago with what was probably unfortunately Marek's and ended up losing three to that. Now my EE Gerty is having trouble walking, shaking her head and had lost weight. I'm sad to say she's pretty thin but I've been watching her eat and she's eating a lot of food. I'm wondering if she has a parasite? I've been giving her nutri-drench the last couple days and put some electrolytes and probiotics in the flock's water last night. It's not presenting like the other ones did so any ideas? When she does walk she stays low to the ground. She was born May 22.
