I don't recall ever seeing this addressed, if it was I missed it. My hen has started laying, and while I am not holding out a lot of hope that the eggs are fertile I thought I would ask so that I can plan 'just in case'. If these eggs do actually hatch, it won't be until towards the end of August. That will mean that the chicks will be 2 to 2 1/2 months old going into a North Dakota winter, and I am worried that they will be too young to handle it. If that is the case, I might have to keep them in the house for the winter. My daughter doesn't live at home anymore, so I figure her room is open to set something up. If they do have to stay in, I figure they will probably be close to 8 months old or older before the weather is settled enough to put them outside. So, for chicks up to 8 months old, how much space should I plan on per bird?
