Not sure where to ask about my silkies weird behaviour recently. I have 2 silkies, both female, almost a year old. I see when they are in the nesting box, busy laying an egg, they put some of the wood shavings on their back. Looks cute though, not sure if normal. Then the other day, the one ate some dried out poop. Why? And then today, the 2 sisters starts fighting over the snacks/food I gave them. They never done this before. Are they just moody or because they are getting older? Please help with advise as I'm still new and learning as I go along.
