Oh no! How awful. One of folks who work for me just had their hot water heater break and flood their living room. The damage can be extensive. I hope it's not too long to put the house back together.

I don't see an overly large comb. The hackle feathers are very hard to judge. The stance does not seem more upright. Right now I would say pullet but you are seeing a lot more of it than I am. Does it have a rooster posture?
