I just wanted to add that my grown daughter used to let her parrot take showers with her, and that parrot was pretty loud. Apparently quite a few parrots like showering, and she learned this from other parrot owners. But chickens do not like bathing in water normally. It is probably just something your friend suggested not knowing about chickens and their behavior—a newbie mistake, so now you know. My chickens will stand in pans of water during the hot summer weather to cool off.
Your pullets may need more daylight hours as said previously. They sometimes can start molting when they have a stress, so look for feather loss. Just watch them for any signs of illness, look them over for lice and mites, and consider worming them while they are not laying.
