I have already placed an order for BR day old chicks (via online) and they will be here in April. After doing some more research I thought it would be cool to get an EE ( for the blue eggs). I only want 1 EE chick, so I'm going to the feed store to see if they have any. They don't get any chicks in till March or April so they will be close in age (would be great if I could get them only days apart). My question is how long do I need to keep them separate (for health reasons)? How do you introduce them to each other?
