Sorry for your loss. The Corid should be given for 5-7 days, and then you can stop. If you want to give the 1/2 strength dose and additional 5-7 days, you can, but then you should stop. The second dosing isn't really done by most people, but people do things differently. It may be better to give the 5-7 day course, then switch to the tetracycline for 7 days. Then you can give them the 1/2 strength Corid or not. After Corid they need some probiotics and vitamins for several days to get back on track.The probiotics can be given at any time, and will help to restore the good gut bacteria. You don't have to discard eggs for corid but you will for tetracycline.
