Feed Withdrawn Eggs to Chickens?

[ker0412]

I'm giving my flock a round of antibiotics. Can I cook and feed those eggs back to my flock during this period? And AFTER the 7 day administration what could i do with those eggs for the withdrawal period?

Hello and welcome to BYC! Glad you joined.
I would feed them back. How long is the withdrawal period?

You could, but would be adding low level antibiotics to their diet through the eggs.

With Doxy I think it is 14 days. But some go longer to ensure residual antibiotics is gone.

I feed the eggs scrambled shells & all back to the flock. After that I scrambled em up for the dogs during the withdrawal period.

The withdrawal period is to keep low levels of the drug out of the food supply, and feeding those eggs back just extends the withdrawal, or make it useless.
Throw them out!

Correct, it does put a low level of antibiotic in the chickens food supply but a typical dosage of doxycyline (DC) is 0.5 g/L in drinking water.
Hens on average drink about 0.5 L of water per day so the amount of drug going into the system is 0.25 g/day.
The peak concentration of DC in eggs occurs middle stage of dosing of the drug and the peak concentration is 12.24 micrograms / g.
An extra large egg weighs about 63 grams so assuming each hen consumed about one egg (which would be a high assumption as not all hens will lay an egg a day) they will then "re-dose" themselves 771.12 micrograms of DC or 0.3084% of the curative dose.
In other words, not enough to concern yourself with when it comes to feeding it back to the chickens during and post treatment.

...and we know this how?
I thought there were very few, if any studies, on drug residue in eggs/yolks?

Egg withdrawal times are there for a reason, and should be followed if at all possible.
