I bought these chicks last week and I guess being that they don't have their mother with them to teach them what to eat and what not to eat, they for some odd reason are very fond of the poop in the feeder (which is the first thing they go for) and they even clean the flooring of the cage by eating up the poop. This is a behavior I just noticed, and it's more obvious being that they're not always interested in eating from the feeder, just from the bottom of the cage. I just thought they found food that was scratched out but no-they find long stuff that dangles from their beaks and they try to grab it from one another! Should I be concerned that they may get sick or something? Is this totally normal?
