I have a four-year-old hen who has basically stopped eating and has had dark diarrhea. I took her to the vet and she did an x-ray and fecal sample And couldn’t come up with any conclusive diagnosis. She prescribed 7.5 mg meloxicam tablet divided into four and to give that once a day and she wormed her. I also had her tested for avian flu and Newcastle. These tests were negative. She seemed to get better after about a week and then start acting the same again so I spoke to my other Vet that I have sometimes taken my chickens to she gave me amoxicillin tablets 250 MG twice a day. I I keep going back-and-forth as to whether or not to give her an antibiotic. I have a liquid meloxicam and have given her 2.5 ml once a day as this vet prescribed. When I dosed her with meloxicam this morning and gave her 125 MG of amoxicillin which is half a tablet. She just acts so lethargic and hasn’t really moved and I wonder if I’m overdosing her I really can’t take her back to the vet because I’ve already spent almost $500 on her can you give me some advice?? I’m thinking that she’s got some digestive problem because nothing else has shown up when when she has been examined by a vet. Thank you ahead of time for your advice and help.
