I posted here the other day asking about combing antibiotics, fenbendazole treatment and corid and the possible harm of doing all at once. The consensus was it was fine. I started the corid a few days ago, after the antibiotics since they both had to go into water. Today is day 3 of the corid. Last dose of the fenbendazole was yesterday. They have capillary worms so had to do the 5 day treatment. Today my rooster is not wanting to walk or eat. When he does walk he is very stiff. He has no injuries or swelling and was completely fine yesterday. My concern is that he now has a vitamin deficiency or aggravated gastrointestinal issues from the combination of medications for the last 2 weeks. I still have a week of the corid to go. I know you're not supposed to give vitamins while on corid but what if his issue is due to a depletion of vitamins? I will say i do have a mixed flock (9m old to 8yrs old) and the stool sample taken was a mixture of several samples. So not sure if he even has coccidia as he's about 3 or 4 yrs old. What would you do in this case? Stop giving him corid and give vitamins to see if that resolves the issue? I called my vet but haven't heard back.
