My chicks are due to ship on 8/11 and with all the talk of chicks being DOA Im getting pretty nervous. The post office that they will be delivered to doesnt open till 8:30 am, does that mean my lil ones will be stuck there till then? Or do most post offices let you pick them up before they open? Do I need to open the box at the post office with someone who works there to check on them? Ive never ordered chicks before so sorry if these are dumb questions!!
