I water outside,, I like to keep the coop as dry as I can,, In the winter I water inside just to keep the water from freezing ..
Once I caught a huge carp,, I split it open and tossed into the chicken yard.. the chickens picked it clean.. but for awhile after, the eggs smelled like fish,, I think it was just from the chickens stepping on the fish and then going in to lay their eggs..
I am also building a table top plucker,, I have a light commercial drum type plucker besides ..
I bought it over 40 years ago,, I have never had to replace a single finger on it .. I did upgrade the motor..
Today I will put the slower motor onto the Whiz Bang plucker..
Go online and there are several U Tubes tutorials on the whiz bang.. watch how slick they take the feathers off..
If you decide to build one, contact me first,, I have made at least 20 improvements of the original plans..
