Interesting thread!
for me, I never again want to gamble on hatchery breeds of any kind. The eggs I've gotten from BYC members and Eggbid have hatched the nicest, sweetest chicks. Can't say how the roos will turn out since they aren't old enough yet. They are BBS Ameracaunas & Marans.
On the other hand, from hatchery chicks I've had both in the past and now, I would never have SLW - she was mean, wild and nothing ever did tame her down.
THe Blue Andalusian I got this year -- that was feathers down the meanest & most aggressive roo I have ever raised, & he was handled daily just like the others (2 EE's & a cuckoo Maran, both of whom are the sweetest chickens you could ask for--they all lay an egg a day altho the marans' egg is only as dark as say, a buff orp or australorp egg-but it's big! - & the EE's both lay nice sized green eggs).
I am sporting a small scar on my upper lip where the Andalusian roo attacked me without warning. He made good gator bait.
