Though the ethical choice is better in your case, I came to realize that chickens (as they exist for agriculture) are kind of strange abominations of what they came from, and they really do live bizarre lives of eating and pumping out eggs. As soon as they're spent they get turned into dog food or similar. Ethically it's better if they aren't trucked around and crammed in cages, but the end result is still servitude in which your body is used until it stops working the way people want it to, at which point you're disposed of like garbage.
In my mind I thought "If I care enough to reduce suffering to an arbitrary point, why not just eliminate it from my diet entirely? Why do I get to decide at which point the chickens suffer the correct amount?". Especially when the more ethical choice still involves the exploitation of the chicken, it seemed like the right choice to stop eating the food they make.
I don't miss eating eggs so it wasn't a hard choice to follow through on. I know some people depend on them far more than I did, or fewer foods are available to them. It's an interesting quandary though and I don't think my decision was the objectively perfect conclusion or anything – it's just worth considering over time.
