Your older girls won't be too much older at that point, so all should go smoothly.
Just keep an eye on those babies and make sure you're still able to separate them again if the big girls decide to be meanies.
And yay, chick pictures!!
I saw a picture of salmon Faverolle chicks yesterday (I don't remember if they were Meyer or not) with just the cutest, fluffiest little cheeks!
I'm psyched for chicks right now! Resisting the urge to add a 10th chick to my order...
Hey, hey, it's 21 days to chick time for me--I guess that means they're setting the eggs for my babies today!
