We got our 6 replacement polish chicks yesterday. 1 was nearly DOA (although it took her a couple hours to finally die), 1 was REALLY tiny and weak, the other 4 looked active and started eating/drinking/exploring their brooder. Woke up this morning at the little one and one of the active ones were both dead. Didn't expect the active one to die at all. The remaining 3 are doing good so far. I'm never doing polish again!
