Please, I need some helpful information. I brought home 6 RIR day-olds and placed them under a broody hen in a nest box about 2 1/2 feet above the floor. This was on Friday, today is Monday. The mamma accepted the babies readily and she and babies have stayed in the nest box all this time. I'm concerned that the babies are not getting much exercise AND I became concerned about no access to food and water so I placed a small container of each in the nest box. Here-in is the dilemma! I don't know if they will ever come out of the box. Should I remove the food and water? Or, should I move mother and babies and place them in an isolated cage? If so, what size cage is large enough? She is very protective and won't let the other hens near the opening to the nest box, but something just doesn't seem right about them being so isolated in such a small space. The nest box is about 1' by 3'.
