Migrated into your cart? I haven't heard that one yet, lol. Silkies are great birds around younger kids (though I can't say the same on the roosters). They're super friendly and some people train them to ride in stollars, if your granddaughter is into that. Easter Eggers (hatchery named Ameruacana) are the ones who'll give those eggs. From my experience so far, I've seen my Whiting True Blues be friendlier than my EEs, if you're looking for the friendlier out of the two. (Disclaimer: I have heard varying reports about the WTB's friendliness, so there might be different strains. Mine was bred for the beard, if that has anything to do with it. )
