I went digging around in my photo bucket to see if I had a pic of my cage. If your interested in building something like this I can try and get better pics of it.
It was a bird cage originally. I took off a panel and built a box and attached it to it to turn it into a rabbit cage. Then I discovered it works for my bantam hens when they have chicks.
The cage is behind the goats head.
My flaws are....the hen doesn't like those hanging out under the wire floor. That would be the cats.
So closer to the floor would be better or use a tray under it.
I wouldn't use chicken wire as I've seen chicks pass right through it. My cage has one half by one inch wire. Another plus to that is rats and cats can't get in.
My box could be bigger. Looks cozy doesn't it.
The top lifts off the box.
Notice the hole is a ways from the floor. To high for the chicks to get out so I put a rock in front of the hole. Now the chicks can get out if they want. The water-er is in the wire part of the cage. Keeps the box dry.
Just some suggestions. Good luck and hope you have a successful hatch. Maybe Thanksgiving chicks?
