Phallus prolapse in drake

I pushed it back in three times, but this morning it had stayed and so far, so good. He seems to be feeling well and is eating and drinking. I'm so glad because I have to go out of town for a couple days tomorrow.

Just keep him away from the girls. Great news it has stayed in.

Yes, he's in with the bachelors now.

So he has relapsed a couple of times since then, and it's now taken a turn for the worse. I have pushed it back, but it won't stay long at all and is quite swollen. He keeps getting white scabs which fall off before more appear, almost like a yeasty growth. He is in with the whole flock again, but I'm pretty sure he isn't mating. Otherwise, he acts fine and happy. Is it possible it could be yeast infection? Would that cause prolapse? I'm not sure what to do at this point. Unpleasant picture below:
