I have a few chicks right now that I have had for a week, so they are about a week and a half old (I think they hatched on the 13th). Seven of the eight act happy and healthy, nice and active. The eighth one, though, I am just not sure about. It is a smaller variety (I don't think bantam small, though). It doesn't come out from under the EcoGlow much. I rarely see it eating or drinking. I have examined it, and there is nothing really jumping out at me. It still acts spry enough, it scuttles away as fast as it can once I put it back. It's just when all the others come running out for the food or to check out what's going on, it mostly just stays under the warmer (I should note that the room is also heated, so it is not particularly cold out from under the warmer). I am just unsure as to whether I should be concerned or if some chicks are just like that. I have had several chicks in the past, but I am not really used to this behaviour after the first few days.
