I keep free choice food and water in the coops at all times. They very likely aren't eating or drinking at night, but I'm sure they do when they wake up before me in the morning.
I am very fortunate that I have dogs and chickens that co-exist together. I will leave my coop door open that goes to the pen so they always have access to water and to go outside. Normally I dont feed them at night but if there is some feed left from the day I will leave it in the pen. My dogs keep a look out for any critters that might be roaming in the night.
Hi i give mine their feed and water in the mornin the ones that i have roamin the yard and at night i go through my show birds in the pens and then they have food all throughout the day along with water i mainly do everything at night so then the next day they already have everything.
