well my three little babies are almost five weeks old! the time flies when your having fun! anyway i dont know, do they still need thier heat lamp? what is there temp supposed to be? and what temp does it need to be for them to stay out all night without a heat lamp?(we have no electric at the coop at this time). they have been staying out during the day (as long as im home!) in a little make shift pen, but i bring them back in at night, or leave them on the porch in the dog kennel with the heat lamp. they are absolutley loving it outside and im thinking it time for the "big girl" coop! im off to get 4 more today and well, all of them in the house may be a little much. oh, and its been well above 60 here most days and at least 45 at night, with an occasional cool night like last night, 35 or so!
