Going to get some peachicks around 2 weeks old - 1 month old. I was planning on keeping them inside the house in a large cardboard box with fresh hay. I ve seen a lot of feet issues with young peas, so i was wondering what y'all think is the best bedding? Should i stay with the hay? or go with a wire bottom? What about sand (if sand, what kind)? Also, how long til peachicks get "fully feathered"? And is a "yearling" a one year old peachick?
