I am in the process of designing a young bird/widowhood loft and like the idea of a mobile take apart loft. I am thinking of an 6 x 12 foot loft with two compartments with a slider to make it one. I think I will make my aviary top the landing board and a trap that splits at 45 degree angles to drop traps. This way one landing board and one trap for both lofts. I also like the idea of the aviary being separate from the landing board. This way birds can sun while others are flying. I will also go with the cheaper wood floor. Also thinking of a shingled roof.
