I have prevoiusly posted this. In a study done by Merck, this is the results. I thought it was interesting.
The margin of safety in laying hens was conducted in 144 laying hens. Safe-Guard® AquaSol was administered orally as medicated drinking water to three groups of 36 hens at 1, 3, and 5 times the recommended label dose (1, 3, and 5 mg fenbendazole/kg body weight/day) for 15 consecutive days (3 times the recommended duration). Another group of 36 hens was provided non-medicated drinking water and used as a control group. In all hens, feed and water intake, body weights, clinical health, mortality, egg production, and egg quality parameters (including egg shell thickness and strength, egg weight, and Haugh unit) were evaluated. Hematology and clinical chemistry parameters were evaluated in 12 hens from each group. At the end of the treatment phase, gross necropsies were performed on 12 hens from each group, and organs weights were evaluated. Histopathologic examinations were performed on 12 hens each from the control and 5 mg fenbendazole/kg body weight groups. No clinically significant effects related to the administration of Safe-Guard® AquaSol were observed for any of the parameters evaluated.

There is no egg withdrawal period for hens being treated with Fenbendazole AKA Panacur and safe-guard.

This is true if the dose is low enough (1 mg/kg) & given 5 days in a row, but the amount you use *does require withdrawal*. I did the math before, and I think the amount you give works out to about 5-10 mg/kg depending on how much water the bird is drinking.
