My 5.5 mo old(i believe) RSL pullet is acting very ill today. She hasn't eaten to drank at all, was wobbling around earlier and "vomitted" when i picked her up earlier. She has a HORRIBLE smell coming from her mouth but her crop feels empty?? And ideas what could be wrong? She was fine yesterday She's laying in a basket next to me right now, but her mouth keeps hanging open and she makes a sort of 'gasping' motion quite often.
