Even though I have a 3D printer, I've solved this for friends by taking
a cast of the gear to make a mold, making a cast of the two gears,
cuting the affected section out of one gear, tracing and cutting a good
piece out of the other gear, making a mold of the new hybrid gear, and
then making a cast of that new, franken-gear with a two-part casting
So far, their gears have run for several years, but I've been able to
cast them several spares in that time without too much extra work.
let me know if you're interested in giving this a try

It was difficult to get the aerial a couple of years ago so I thought it might be quicker, and therefore safer for my chooks from fox attack, for me to get that part 3D printed. Hence my off topic request. Alternatively, I have to try and find the same aerial or rebuild another chook, hatch system to suit a new aerial and that leaves my chooks open to fox attack for longer.
