The other day after raking out my chicken pen and loading it into the wheel barrow, my ever curious dog tipped it over b4 I had the chance to get it to the compost pile.It then started raining, so I left it out there. After letting the chicks out this morn (they 'free range' during the day) I noticed them picking through the poo<sorry,I can't think of any other way of putting it>. Are they missing something in their diet? (Their food and some veggie treats were like 10' away,and they choose to eat their own p**? I stopped giving them grit awhile back,since someone said they REALLy don't need it since they free range..Any ideas?
