Hi all, I guess I need to understand the reason behind roosting and if and why the chickens need to do this. I have 3 silkies (3 months old) that still sleep on the floor of the hen house. I saw somewhere that once they are a bit older you should place them on the roost at night to get them used to sleeping this way. Is there a certain reason why they need to roost? Or is it OK for them to sleep where and how they choose (which is my thinking...). Thanks!
