We have 13 laying pullets (about 9 mos. old). Only 3 have/had any type of swelling, but some of the other pullets currently have that same small scab on the bottom of their foot. Can they have this scab and not develop bumblefoot (full blown infection) or does this scab mean they already have the infection and the swelling is inevitable with time? Do I have to actually cut any foot with a scab or will these chickens be fine if I leave them alone? Cutting into their feet was awful - I dread doing anymore. I did 5 feet total (among the 3 hens) and think some of the surgery were successful, but couldn't fine the plug everytime.
The bandages are still on - I figured out to wrap them around the feet so that they don't slip off (using something similar to vetrap, but by Johnson & Johnson).
I'm not sure exactly how they're getting the bumblefoot, but have a couple ideas:
We live on a 1/2 acre lot - the backyard is 1/2 grass & 1/2 rock landscaping. Desert rock landscaping is popular here in AZ and the previous owner added LOTS of rocks to his yard. There is still plenty of grass for the kids & animals, so the rocks were never an issue till now. If the rocks are the problem, then I may not be able to keep my chickens - there's no way we can get rid of all these rocks (we did remove as many rocks as we could from their run, but they still walk & run on the rocks that are outside the run while free-ranging).

This is the coop - I'm still removing rocks from it -- have been for the last several months. We've added sand to the dirt, but every 10 days or so, I go out and rake up the new rocks they've unearthed.
I just went out and measured their main roost. It's 38" high. In case that's part of the problem, we're going to lower it another 6" (I'm trying to keep it higher than their nestboxes). The area under their roost is linoleum over a wood floor with a couple inches of shavings (I'll add more shavings). The roost is 3" wide - maybe it's too narrow? It's painted and there are no splinters.
