Yes, the eggs would be alright for consumption as with so many other treatments used for various maladies except as you say for antibiotics. You can't avoid getting around treating with antibiotics for some maladies and I've had flaming feedback from ppl violently opposed to even use of certain antibiotic brands but I like my vet's cautious and thoughtful approach to treatments he prescribes. So I continue sharing my experiences and leave others to form their own conclusions especially if they've thoughtfully done their own research.
I see so many posts throughout BYC where novices who never had poultry want to know how to go about selling eggs to help with flock costs. Research, research, research, BEFORE attempting to do anything that requires transactions with the public. Probably one of the main reasons CRD has been spread on to such a high percentage in U.S. backyard flocks - including customer claims that reputable business hatcheries have shipped unaware of disease or bacteria in their chicks. The latent diseases classified under the CRD umbrella can be one of those silent culprits that doesn't scream in advance "Here I Am!" so I love breeders who openly share the susceptibility in certain breeds in their reviews rather than hiding such information. The subject comes up in so many BYC posts.
Husbandry laws are in place for a reason (of course seeing them enforced is a whole other subject!) but I digress. The more I research the less I discover I know even though I was raised on a farm. Animals are a huge responsibility - on the equation of having children in my mind. I was fortunate to advise one potential chicken owner - assisting him in evaluating his requirements and alert him to the responsibility and expense of having such a "hobby." Besides no knowledge of chickeneering he had absolutely NO space that would allow even a small flock to remain healthy. I applauded him for doing the research BEFORE acting and he came to his own realization about the limits of his particular situation. Just because your city is zoned for livestock doesn't mean you plunge into chickeneering without research.
I love your input as you eloquently add and cover much information I might leave out in these posts.
BIOSECURITY is the key ! I like many people derive great pleasure from my birds but I never forget that they are livestock . I sell fertile eggs and grown birds for showing and breeding. I do not bring any birds in from outside and that is the only way to protect my flock. It's also worth remembering that mosquitoes, water birds and vermin transmit diseases such as CRD and mareks. Mycoplasma has been known to survive 6 weeks in sperm so being that the incubation period of the egg is only 21 days , it's no wonder there are so many poor little chicks in trouble from day 1.
Our experiences and input here on this and other threads will hopefully help others.
