It does help if you have a lot of flexibility. I work from home and forget the time constraints of others in that regard. It does add some complexity to getting chicks from Sand Hill.Honestly, I'd be up for trying their birds in the future, the only downsides are how they accept payment and that they don't have concrete dates for shipping. I can't just take off time all of a sudden to accept chicks, I have to plan it ahead by a few months.
Maybe it's changed since I last looked, but that's what stopped me the first time.
The way it works is you get no notice until a Tuesday evening, when you get a call with the tracking number. Typically that means your chicks will arrive at your PO on Thursday around noon, but it could be Friday sometime, or even Wednesday. Really hard to schedule anything around that. Getting someone else to pick them up while you are at work is not the best, because they really need some specialized care after the stress of traveling.
