Sorry for your loss. I'm trying to figure out how to deal with a similar hen of mine. First time I've seen this type of thing before. Felt around her abdomen and it feels like fluid. Not sure what egg bound would feel like. I'll give her a warm soak in a dish pan and check her vent as you did.
Half inch cloth is better but if you want to save the $$ some people use welded wire covered by a layer of regular chicken wire. Chicken wire rusts out quick and I don't feel like doing it over so I went a good guage cloth.
That's why I'm switching. Space is an issue but also more maintenance than I'd like with 24 birds. Ideal for 12 or less though. Hammock sounds like a good idea. What material did you end up using?
Walmart has usa made galvanized drip pans for 11 but I think they are less than an inch deep. I'm trying to figure out a different setup to change from pdz litter.
I like pine shavings but the chickens keep kicking it to the walls leaving the middle bare. Maybe I'm not spreading it thick enough. Straw always seemed to work well.
I'd make a good sized permanent coop with a couple different popdoors and just rotate the electric fencing. The tractor setup sounds like a lot of work with that many chickens. Just make sure they are layers and not retirement hens :)
The majority of people here recommend the wide side of a 2×4. If you want to go round I'd use a good size somewhat straight limb about three to four inch across.
This is what I am thinking about making. Not sure what to fill it with. My garden soil had a little bit of lime tilled in this spring. Would that be okay for the chickens?
As long as you have comfortable roost space I'd go as big as you can with the run and at least partially covered. The run should be close to 12×16 for 20 birds if possible.
The roost is usually around 48in but they will go higher given the chance. I had to block off my shelf and 8ft ceiling rafters. Just make sure the floor is padded well with bedding so they don't hurt their feet coming down. A general size for nest boxes is 12 inch square for standard breed...
