In case what I posted before is science or medical or whatever we are now not supposed to talk about - I've been trying to understand what might happen and why (as this situation or as a hypothetical) - not trying to bash in any of my posts.
Intersex in various species makes sense to me whether it an unusual hormone production (or exposure - such as the free martin heifers) or unusual sex genes (extra copy of one or the other kind, for example). Possibly there are other ways.
Sex reversal, though.... what did the vet mean by that? I can think of several things it could mean in the context of chickens. Some known to be possible; some not possible.
- It could mean a male looking like a female from hatching
- It could mean a male looking like a male from hatching until something happens so that he doesn't
- It could mean a gene therapy type change
- It could mean a chicken capable of laying a fertile egg changed to become a chicken capable of delivering viable sperm.
- Other options
And the vise versa male/female for each of the males and the females in the list.
If it were the fourth option - what changed? The entire system (is what it sounds like is being proposed, but maybe I misread)? How would that work - one was absorbed while the other grew? He had two reproductive systems? Not just two but one of each?
Or did the ovary or ovary part of a gonad (and the parts that added the albumin, the membranes, the shell, the color, the bloom) work for a while and then the testis or testis parts start working a chicken that had one system that worked for both?
