This is my first time raising chicks (1 BO and 1 RIR), and they are almost 3 wks old. I notice they only eat directly from the feeder. The BO in particular likes to stick her head in the feeder when it is newly filled and dash feed all over the place. However, neither of them will touch the spilled feed. Besides not appreciating all the lost feed, I also was hoping to use the deep litter method once I've put them in their coop. I understand that part of the success of this method depends on their scratching about and mixing all their dried poo with the litter. Right now, in the brooder, their poo just stays on top, so I'm covering it with fresh pine shavings every couple of days, which is more frequently than I thought I had to. Any insight would be greatly appreciated.
