I feel it is important to mention that my birds have already been through a bout of Cocci in May, one of my birds passed for it but i managed to get a fecal float and treat the rest. I know that this can predispose them to enteritis
i am most worried not that the bacterial infection will not pass, but that she will not be strong enough to fight it. She has not been laying, she has lost significant weight, and she is not eating as much as she should. She has been drinking a lot, just not really eating. I even gave her scrambled eggs (she usually loves) and she did not seem that interested. She seems more interested in roaming the basement when i let her out of the quarantine bin. I’ll try oregano, as well as the antibiotic i hope to get. Hopefully she will be well enough to re-join the flock in a bit. I put her out briefly, but she was miserable and fluffed up in a corner.
also she has not been laying. She was in the beginning of the illness, but suddenly has stopped sometime during the duration of the illness. Not surprised considering how underweight she is
You are a commercial farmer, so can not just give antibiotics without researching which are allowed and what are egg withdrawals for the approved antibiotics.
That antibiotic you found is enrofloxcin. I use a lot of enrofloxin where i live, but if you are selling eggs, I cannot recommend enrofloxacin because it would be violating the usa laws and regulations regarding commercial poultry. I am just a pet keeper and live outside the usa, so the rules dont apply to me, only for commercial hens which you have. I eat the eggs no matter what medicines i use generally.
Enrofloxin probably cant be used in a commercial hen. Be very sure you can use this in your laying hen and still sell the eggs, the egg withdrawal period is undefined because it has been banned in poultry. But if you read around on various research, two weeks is adequate.
Terramycin (Oxitetracycline) would be a better choice for your hen. But I dont know if it is available in oral in the usa, and i dont know if you would be comfortable making an oral solution from a gel.
If you do use it, be very careful with enrofloxacin dosage. Too much can cause irreversible harm to the hen.
Another off the books idea, neosporin contains bacitracin. You could give her some neosporin mixed with water orally. But really that is something I maybe would do, but never had the need to. The worst side effect of consuming neosporin would be if your hen had an allrgic reaction. So you could dose your hen with bacitracin by giving her oral neosporin.
None of the ingredients are fda regulated, except you have to check the egg withdrawal for all three antibiotics in neoaporin. Its probably a bad idea again because you are a commercial farmer.
Interestingly the ingredients in neosporin are all edible. And it contains the original antiviotic you were looking for.
