I got wt doe in heat all over the place with wt bucks chasing non stop. Also have several axis bucks on property and have not seen a single axis buck even put their nose in the air when around a wt doe in heat. Also have seen axis doe in heat around wt bucks with no response.

I don't think it happens in the real world.

I was curious about if they cross or not. I heard about the crossing with hog deer in zoos.

Black Eagle in Harper has a strong herd of both Hog Deer and Axis Deer. They keep to themselves.

On a ranch elk, red deer, or sika usually won't cross breed, but you put a elk bull in a pen of sika does you will get a bunch of hybrid fawns. In a small 10 acre pen you will have cross breeding take place. In the early 90's I was at the Priour ranch looking at Dale's mouflons. Dale pointed out a hybrid cross between his Dyboski Sika and a Axis. He said that was the only one he had seen. I have seen besides that one a couple of others that were crossed (axis x sika). I bought the last one that I saw. It was a doe. She looked basically like a sika with bright white spots. She hung around with the axis, but she always bred back to a sika. I raised several fawns from her. One other thing about her, she was cold sensitive like a axis. I eventually lost her in a ice storm we had. None of those crosses that I mentioned were planned. They were in small inclosures and it just happened.
