I have eggs under a hen that should be hatched in another 7 days ... 1st. time at hatching baby chicks so I have alot of questions . How soon do I start them on chick starter ? How long do i keep them on the starter before switching to the next stage and would that be GROWER ? What age is it ok to MIX these new chicks with the rest of the flock ? Will the mother take care of them and protect them from bullies ? I have separated the HEN with her nest and eggs into a cage . Once eggs are hatched , HOW long before I put her back with the flock ?
