We just picked up some chicks from a hatery somewhat near. When we left they weren't even fully fluffed out. When we got home I dipped their beaks in the water, but none of them started drinking it. I know they got some because they tilted their heads up and made gulping motions. But none ventured on their own. Should I keep introducing them to it every so often? When should I expect them to eat and drink? Thanks!
