We just dealt with this same problem. A very cute, very big raccoon attacked our chickens at 6pm one evening and killed one. I always put them in a predator-proof coop in the evenings, but usually around 8pm. It looked like the hen suffered a lot and this was heartbreaking.
We put out a large no-kill trap baited with cat food. Our local ASPCA will pick up animals caught in live traps. Unfortunately (?), the raccoon was caught, but found its way out of the trap. There was a lot of blood left behind and we suspect it was injured and hasn't come back.
I grew up on a farm, but live in the suburbs now. I don't have issues with wild animals because they're just doing their thing and they are natural parts of healthy ecosystems. It's my responsibility as a chicken owner to keep my pets safe. However, raccoons (especially with babies) become very territorial. If you can, as others suggest, I would contact animal control and see what your options are to rehome them.
