We put a couple of blocks for he oldest to climb onto so she can toss treats in through the bigger openings in the upper fencing. She loves tossinghandfuls of grass in for tthem.
We'd like to either build some steps here for the two year old or cut out a small opening in the 1/2" hwc and tie in some of the 2"*3" fencing down low with 16 ga wire so that the younger neighborhood kids and oour two year old can come visit and toss in treats if they like.
We also made a small wet feed station. Its just some scraps of 2*4 screwed together. On one side we added a cheap plastic dollar store bowl. We drilled a pilot hole into it and used deck screws and rubber washers to secure it to the wood block base. It gets scraps of soggy cereal, milk, yogurt and the likes. The other side currently holds their tiny waterer (not secured down to the blocks). We'll build a water station soon but we will add a larger fermented feed tub to this side later.
We fastened all the hwc to the framing with deck screws and washers, every 6" or so. The upper fencing is stapled in. It overlaps in some places.
The ramp is two pieces of thin plywood glued together. It measures 12" by 72". The cleats are made up of 1*2 furring strips every 6". The cleats are attached via deck screws and the whole thing was caulked well and painted to match the pop door.
The chickens seem quite content. We only have six birds and about 74 square foot of run space.
