We just brought home our 4 little ones. They are 3 or 4 days old. How do I know if they have enogh space in the brooder we set up? We put the water on one side and the food on the other side is this ok or do they need to be together? Also I have read a ton of information from this site and it has been so extremely helpful. I would love any advice you can share. 1. How do i know they have enough room? 2. When can I start giving them treats and how do I give them the grit?
