I just received my new chicks! Yea! I have 31 and they are in a large kids plastic pool with cardboard around it and a heat lamp but some still seem cold and others fine. They have only been in there just over an hour and all have had water and starting to run and eat. They also seem to pick at each other a lot. Need lots of advice ! Very new to this and don't want to lose anyone. I have 2 smaller ones that seem cold and not sturdy enough to huddle in the bunch to warm up.Any advice is welcome!
