Thanks everyone.
They all survived a cold night last night and it will be even colder tonight.
I checked the temps in the brooder and it was 45 degrees in the far corner of the brooder. So, it was warmer nearer and under the light, which is where they were.
I checked the bedding and I cannot believe how bad the bedding looked. The bedding WAS so fluffy and big on Sunday evening. Now today (Tuesday morning, the bedding looks like this. It doesn't look like I can turn over the bedding or replace a few patches. It looks like I have to change out A LOT of the areas that are smashed down with poop. How often do you all change out your bedding and what is your process for changing your bedding? I know that everyone's length of time will be different based on how much poop the birds expel. Looks like I have to get more bedding. I hope that I"m not averaging a sack of bedding every 1 1/2 to 2 days. Those shavings are expensive ($4.99)
