***Info re Egg withdrawal.

Medications require different amounts of time to be eliminated entirely from the hens body.

Many drugs have an established withdrawal period because the appropriate testing has been done.

In many cases the egg withdrawal period is for the duration of the treatment plus one week after.

If drugs are prescribed by a vet “off label”” ie a non approved drug to treat a specific set of symptoms, based on clinical expertise, no specified withdrawal period may exist.

In this case, you may be advised to withdraw the eggs for 28 days.

Reasons for egg withdrawal.

Certain drugs are absorbed into the hens body. First into the blood stream and tissues, and is then eliminated via the liver and kidneys. Drugs are eliminated at different rates.

Substances can be deposited in eggs 10 days before the egg is laid so if using a medication for meat birds, it may be prudent to add 10 days to any specified withdrawal period.

Antibiotic residues in meat and eggs may cause a severe reaction in individuals who are allergic to antibiotics. A disturbance of the gut flora may also occur.

****Please note….this information is for general guidance only.

It is entirely your responsibility to seek the appropriate professional advice before administering any medication to your hens.
