Hi, I have two incredibly broody silkies that I took pity on. I got fertile eggs from a nearby farm for them to hatch, as I have no roosters (in burbs). Should I be treating them differently now? Should I provide extra food/treats? Also, at what point should I move them from their current location (in the main coop with two other birds who can be aggressive), to a coop where the chicks will be safe when they hatch? I don't want them to abandon the eggs, should I wait until they have hatched? I'm fairly new at this, I got all my birds when they were already at least sixteen weeks old.
