I really don't think you were at fault. It may just be one of those things. And the temperature swings sound like the most likely contributor.Good points. Temperature I think was a factor. Her birds were off heat but our temps suddenly decided to do extreme swings & on top of the stress of moving plus anything else that might have been going on I think the smallest didn't cope. Lesson learned. Won't ever be getting them that small again.
Depending on rarity of breed I expect to pay quite a bit more for POL. That is the usual practice round here. Chicks are cheap & there are lots of loses. POLs have proven their hardiness. One thing I look for is cleanliness. Despite the numbers of birds there is absolutely no smell @ all. Someone that careful about their keeping practices is probably careful in other matters too.
I'm not discounting the breeder could be @ fault but if I'm honest I think the fault is most likely mine. I'm sorry the birds paid the price for my ignorance but I will know better another time.
