Pigeons are remarkably versatile when it comes to feeding. That mix sounds OK to me. Access to grit is necessary, but any ground contact should suffice.
With a lack of pigeons feed available in many parts of the country, most people I know use a 50/50 ratio of mixed birdseed and chicken feed.
I can't help but think a calcium supplement might be beneficial with that mix too, more for the chickens than the pigeons. Crushing and refeeding eggshells is the easiest way to go about that.
Moving them around chicken tractor style would work if you had non-breeding pigeons. Most utilities have squabs or nests all summer long, and unlike rabbits, they have to have constant access to their young.
For a reference, these babies are 5 weeks old and still haven't joined their parents at the feeding tray, they are still 100% dependent on being fed. Sometimes the parents will start to sit a new nest while still feeding the last clutch.
