I had a worry wart night last night and have three new questions: 1.) Last night when I was changing the cage, I noticed that a lot of them had food, etc stuck on their chest like they had laid in crud and it had dried. So I took a warm paper towel and washed it off, but some of them have NO hair/feathers on that spot now, just bare skin. I didn't scrub, just lightly brushed the crud away, so where did the feathering go? 2.)Now that they are 8 days old, can I use pine shavings as their bedding? 3.) I noticed that my two BO (?) chicks have bald spots, but I haven't seen any of the other chicks picking at them. Am I just not seeing them pick or could it be something else? Thanks to all. I feel like the mom who takes her kids to the emergency room everytime they cough!
