Hi, sorry your flock has been ill. I'm new here certainly not a pro, but I'm giving one my girls Tetracycline Hydrochloride also and was wondering how long I had to wait before eating her eggs & found this page from the FDA on someone else's thread

http://www.fda.gov/AnimalVeterinary...lDrugProducts/FOIADrugSummaries/ucm118116.htm.
.
FDA says 4 days calls it "withdrawl time" Folks here on BackyardChickens refer to it as 'toss eggs".
Hope that helps. Best of luck. Susan

Welcome to BYC. Many chicken people use tetracycline drugs on their chickens for respiratory diseases. The usual egg withdrawal time is 21 days from the last dose.

I though this was interesting:

Oxytetracycline
There are many papers looking at egg residues from oxytetracycline treated hens. Oxytetracycline
is approved for laying hens in Canada. Soluble powders labelled for use in the drinking water at
doses of 190mg/gallon to 424 mg/gallon have a 60 hour to 5 day egg withdrawal respectively.
Since there is no tolerance for oxytetracycline in eggs in the US, a longer withdrawal interval than
Canada’s recommendation would need to be observed for extra label drug use of oxytetracycline
in laying hens.

Chlortetracycline
Chlortetracycline is approved for laying hens in both Australia and Ireland. In Australia,
chlortetracycline is labeled for use in the drinking water of chickens up to 60 mg/kg/bw
for up to 5 days with a zero day egg discard period. In Ireland, there is a medicated feed
containing chlortetracycline to be fed to layers at a dose of 20 to 25 mg/kg bodyweight
for 5-7 days with a 4 day egg discard. Since there is not a tolerance for chlortetracycline in
eggs in the US, the withdrawal interval for any eggs undergoing regulatory inspection would
need to be extended to allow residues to deplete to a level below detection.

@perrymom47, ask your horse vet to submit a withdrawal request for you. The form is here: http://cafarad.ucdavis.edu/farmweb/index.aspx
