I want to know about placement of the roosting bars.  Some are round, some are 2x2, 2x4 etc.  I felt like the 2x4 placed with the 4" laying flat for them to sit on would be best but......... I have found all kinds of ways.  I live in far south Texas and I don't worry about frostbite here (which seems to be of concern to northerners) Any advice on which way to install the roosting bars.
