I spent the day making my two Prevue Hendryx F050 cages into one giant one and it is amazing. My budgies are going to be so happy. Here is how I did it.
First I unscrewed the top bolts holding the right side roof on and pulled out the right side top panel. Then I screwed it back together.
Next I unscrewed the middle right side bar and removed the bottom panel. Then I screwed it back together turning the bar so that the holes were on the side instead of on the top and bottom.
Repeat for the left side of the second cage.
Remove the front left wheel on the right cage and the back right wheel on the left cage.
Place bolts through the holes of the middle bars and use a cap nut to bolt the cages together. This holds everything together except the very bottom is still loose. Right now I just used zip ties to hold them together. I hope to find a bracket that I can use to hold the bottom frame together. The goal is to find a bracket where I can unscrew the screws of the bottom of the frame, put the bracket on and put the screws back in. It did take two people when I got to the part of putting them together.
Anyway it is awesome and I am sure they are going to love it. It is 6 feet 2 inches wide x 23 inches deep by 60 inches tall from the floor to the top. I have 10 budgies in it. I think I would prefer to have 8 in it but I have 10. When I had them split up in the two separate cages they used every inch of it from top to bottom so I think it will be better now that they all have use of the full space. I will do my play place next.
