It might be possible according to what I've read, but you'd have to start ACV way before the breeding season.I've recently heard that ACV can cause a higher pullet/cockerel ratio in hatches. Does anyone have any experience with this? I think it would be awesome if you could actually hatch more pullets than cockerels by doing something as simple as adding ACV to the parent's water. This year, without ACV, I had a 4 boy/3 girl hatch rate (which I didn't like too much). This spring, I am going to see what affects the ACV will have on the hatches. If I could wind up with about a 7 girl/2 boy ratio, that would be fantastic. That might be asking for too much, though.
