Hi everyone, I actually rang the company the makes Tylan and was told this.
In New Zealand their is no waiting period at all before you can eat the eggs. They eat them all through the treating process.
I asked the man would he then do that, and he said to me that in all honesty it is up to me, but he personally would wait 7 days.
There is your answer to the question can you eat eggs whilst your chooks are still being treated with Tylan.
