We are raising our first group of chicks ever and one of our chicks, a blue Cochin, keeps having this weird momentary paralysis. It's happening at night when they are about ready to go to bed and we are cleaning out their brooding box to ensure there is no wet bedding and to get rid of most of the poo we see. It's happened to both me and my husband where we pick her up and she totally freezes with her legs out like they're paralyzed. Then when you try and set her back in the brooder her legs are still frozen for about 30 seconds to a minute then she stands up and seems just fine. Is this something we should be concerned about? Is this just happening because she's scared or is this a potential sign of something wrong? Thanks for any help you can give we are new at this and would really appreciate your expertise.
