My two year old hen started on clavamox a few days ago. It's for a possible infection of her shell gland. She has been laying soft shelled eggs for two months after nothing for six months. Three days ago she started 275 mg of clavamox twice daily. She has become extremely lethargic and vomits every time I pick her up. She also has clear diarrhea. Giving her the pills has been a real chore between the vomiting and her wiggling even though I wrap her in a towel. Does anyone know of these are normal side effects? She will be on the drug for a total of ten days. Thank you!!
