In the Brooder
There is no egg withdrawal with Tylan given orally. With injections, there is a 1 week withdrawal for eating the eggs. It might be a good idea to wait a year before new birds just in case it is infectious bronchitis, since birds can be carriers for up to 5 mo-1 year. If you every see any with swollen bubbly eyes, then that can be mycoplasma, and they can then be carriers for life. Many vets and experts seem to think that mycoplasma is pretty common in most backyard flocks. Many people here on BYC will have differing opinions on separation and closing a flock. If you ever lose one to a disease, it can really be useful to get a necropsy by your state vet, since that is the best way to identify a disease.
Will the egg toss apply to the rooster? He is injected with Tysan and mates with the laying hens.
