Hello again! Okay, so we got a second batch of chicks (6 more)last Saturday, for a total of ten again. One died the first night (bottom of the pile), and none since, so we are at 9. They all seem healthy/perky/etc. We switched them to wood pellet type bedding, since that's what they were on at the feed store, but that bag is almost gone, so is it okay to switch them back to pine shavings now? They all have to be at least 2 weeks old, because we got the first batch 2 weeks ago, and the second batch was from that same shipment (the last for the year). So, I have no idea if the shavings were an issue to begin with...but is there any way it should be a problem now?
