My 4 black australorps will be two weeks old on Sunday and they are really starting to get the hang of the whole flying thing. They have a pretty large brooder box (rubbermaid tub) with lots of room to run around and flap their wings...which they have been doing a lot! One of the chicks has apparently decided it is fun to jump/fly its head into the hardware cloth I keep on top of the tub. Others flap themselves right into a wall. When I am holding them, I always sit on the floor because they like to jump/fly off of me, and they don't really know the meaning of "graceful landing." It is funny to watch, but I am getting concerned that one of the chicks might injure itself. Is there something I need to do to protect them? Part of me want to wrap them all in bubblewrap
, and the other part of me says they have to take their tumbles just like any baby growing up.
Any advice?
