I have a couple of 4 day old little snowy mallards, 1 boy & 1 girl. All of a sudden the little boy will just take of scooting really fast to the other side of the brooder. It's like a major ZOOM! Sometimes the little girl (LuLu is her name) will do it too but not as servere. Anyway, is that normal for them to do that? Is he just playing or what? It is pretty funny when he does it but he goes so fast he can't stop & slams into the other end of the brooder. As I sit here watching I am thinking that maybe he is playing? I am new to duklings so any advice or knowledge would be helpful! Thanks!!
