I've seen some of these threads about introduction of different age chicks, but none where the difference was only one week. I'm scheduled to pick up my first 2 chicks (EE and SLW) on 3/30 at the hatchery, and 1 additional chick (salmon faverolle) on 4/6. I can only have 3 chicks to start with, and I keep calling the hatchery to see if they've had any cancellations so that I could consolidate my order to one day, but so far no luck. Any advice for how I should introduce the new gal? Will she be ok? Thanks!
