How big can they get?
at this point its out of control.

let me explain. this ugly pile of sticks was a play set in the my inlaws neighbors yard. the roof is shingled and was about 12-14 feet in the air. it took 6 people to lift to the ground and load on my trailer. it sat all winter in the yard on saw horses. I got a bug in my butt to build a deer blind to hunt from. I hate sitting out in the rain. with the help of my son I managed to make what in the picture above. by the time it was done I had this.

put it down in my back field and it didn't get used for a year or so.
then came the geese...
I needed a bigger bird house. so it got tore apart and things got weird.

I had read about some English bloke who came up with this slatted floor. he used it for ducks. I upped the anti going with geese. they make a mess.
I cut the floor boards on a 15* angle and they gave a 1 1/16" reveal on top. thats enough that the feet of the animals are supported. however the gaps are 5/8"-3/4" apart to let waste fall through. every board and wedge is nailed and glued. this took a whole week while I was off on knee replacement surgery. it was tough but I got it done.
the blind turned coop has been changed a bit.
the best part is once it sits long enough I move it and rotor tiller the waste under and make way for a future garden spot.
