@Willow- There has been only one correct answer since you answered correctly. You have to wait for two points to be awarded before you can answer again. You answered BTownChickMom's question correctly. I posted a question since there hadn't been a question in 12hrs and <3CF answered it correctly and asked a question. So you have to wait for one more before answering.
<3CF's original question can still be answered by another person.
Post the link to the learning center article on chicken FAQs and post the answer to this question on that page: What is the best material to spread on the coop floor?
