Can the hens eggs be consumed when medicating them with Doxycycline 20%?

[natyvidal]

My flock has a cold! Runny noses and what sounds like a funny cough and sneezing! So I am giving them Doxycycline! In their water. They are laying and giving me a lot of eggs.
Question is: Can I cook the eggs and give them back to the flock being treated? Will cooking the eggs destroy the effects of antibiotic? Can I give the cooked eggs to the flock that is not sick? The ones not getting the antibiotics?

So they are getting the doxycycline right now. But, I am running out of it and planning to continue with Denagard 12.5%. Same questions apply for both antibiotic.
Thank you!

Look at the FARAD.org website for information about egg withdrawal times after using that drug. Feeding the eggs back to the birds just increases their exposure, not helpful. Those eggs should be discarded rather than having a very low dose of the drug eaten, which helps develop antibiotic resistance, not a good thing.
Hope your birds get better! have you tested them for Mycoplasma?

Thank you Mary for the info. I don't want them to develop resistance to antibiotics. The eggs will be disposed! It's a damn shame though. They have been slow in laying eggs and just now they started again. I will also check FARAD.org since I will also need to know for how long should I discard the eggs. Thank you.

Doxycycline or Denagard are not approved for poultry as most antibiotics are not. Doxycycline can be found in egg whites or yolks for up to 14 days after completion of dosage. Apparently there is no egg withdrawal in Europe for Denagard, but I haven’t found any other info. It is always good to try and get testing to find out if you are treating a virus, which does not respond to antibiotics, or a bacteria or mycoplasma, which might if the right antibiotic is used. But if antibiotics are used, you probably won’t want to eat the eggs.

Thank you for your response. I have two flocks. One is for meat chicks and eggs. The other flock is layers.
The two flocks are kept separate.
The meat birds were the first ones to get sick. I have already treated them and after 14 days their cold is gone. The layers got sick later and I am treating them now. The fact that the meat birds responded to the antibiotic treatment tells me I am in the right track. It's not viral. It's bacterial.
And I do agree with you. Although it hurts me to discard the eggs they will be disposed of.
I appreciate you letting me know also about the removal and lasting effects of the antibiotics on the eggs. I will switch immediately to denagard since it seems I might not have to wait as long to sell and eat their eggs compared to doxycycline.

I tried to research the website FARAD.org about the effects of antibiotics on eggs but could not figure out navigating it. But, thanks to your observations now I have the answer.

Thank you.

Tylan or Tylosin is approved for poultry, and given orally, requires no egg withdrawal time. It is for treatment of MG in chickens and birds. Here is the only article I can find with info on Farad, although a few years old:

Here is a link for Tylosin powder:

The FARAD site was 'improved' a couple of years ago, and it's more confusing than it was. At the bottom of the home page, in that list of sites, there's 'species specific' sites, go there, and then to 'backyard poultry'. Also the 'approved drug list' area.
The list for chickens is pretty short! There's also a section about drugs approved in some other countries.
