I went my my feed store and was told I should treat all the chickens with Duramycin-10.They are not free range and there life depends on it due to my dogs.Catch has 4 hens he lives with. None of them have a problem with there comb.Now how long do we have to wait before using the eggs if they all get the Duramycin-10?Also how much do I give them and is it for 7 days or 14 days? The package is a powder (6.4oz) and has to be mixed.
