Can 5-week-old chicks still smother each other by sleeping too close together? My cardboard box brooder got soaking wet (thanks to a tipped over waterer) and I've had to make an emergency replacement brooder that is not as large. THey are all crowded together - but do have the option to walk into another cardboard box that is attached (they've had that set up for several weeks now - ever since the first box got too small). Are they smart enough to spread out in to the second box if they are too crowded in the first? Or do i need to quickly scramble and get something else tonight? I'm hoping to have the chicken coop cleaned up well enough to move them out this weekend. Thanks so much for your advice!
