What is wrong with this kit’s fur?

[Aviodont]

These 10 kits were born day 32 (early yesterday) to a Chestnut Agouti NZ and a blue Standard Rex (black doe and blue buck). I call them my Hurricane litter because in the early morning hours as Hurricane Helene ripped the roof off their hunny hutch at 5:30am, my wife and I rushed into the dark and pulled the wet rabbits from their cages and put them in bins temporarily as we searched for candles since the power was out. Well, by phone light, I looked to my side and saw one of my bucks had hopped in with a doe, fallen off and well, you know the rest.

The largest kit has something weird with his/her fur on the right shoulder. Based on the two photos, Any ideas?

Just looks like a small patch that got dirty and dried

Looks like some urine dried on there to me. They will start grooming themselves very soon and should clean that right up.

We had a SF kit with a similar mark. It looked like the mother had stepped on it and her toenail pierced the skin slightly. It even had a little piece of hay embedded in it. We removed the hay and left it be. The mother did her cleaning and it quickly healed, eventually filling in and was never noticed again.
