Tramisol is Levamisole. Here is something I found about it's withdrawal.Well, the vet called me and I asked her about de-worming my hens.
This is what she told me:
She does not routinely recommend de-worming because of where we live.
She does not worm her hens.
She also wants to keep the 'sick' hen where it is warm for another few days or so.
Not a problem, I like having her inside.
Oh the debate of deworming!
I went to pick up lay mash and talked with my feed supplier.
He recommended worming the hens with Tramasol, being that the whole flock of 4 are a bit thin.
So I went to the local vet supply store and got some Tramasol.
Now I want opinions on this before I dose the hens.
I'm off to the internet to get information on this stuff.
Also got some electrolytes to add to their water.

Abstract
Levamisole is currently being used to treat capillaria infection in chickens even though there is no published withdrawal information available for levamisole in chickens. Tissue residue withdrawal of levamisole in chickens was studied in 32 healthy broiler breeder chickens at the age of 32 wk (peak of egg production). Levamisole residues in chicken tissues, eggs, and plasma were determined by HPLC with ultraviolet (UV) detection at 225 nm. The highest level of residue and longest withdrawal after oral administration of 40 mg/kg levamisole to chickens was in the liver. On d 3 the level of levamisole were undetectable in the plasma. On d 9, levamisole residue in eggs was 0.096 microg/g and on d 18 it was 0.06 microg/g or less in all the analyzed chicken tissues. Those levels were lower than the recommended maximum residue limit (MRL). The withdrawal time for levamisole in chickens was longer than for other species tested, which is due in part to a larger dose of levamisole being recommended for chickens. In conclusion from this research, 9 d are needed for levamisole in eggs to be less than the MRL, and 18 d of withdrawal are needed before medicated birds are slaughtered if their tissues are to be safe for human consumption.
