I have a 7 month old rose comb bantam that decided to set just as it began to turn cold. I thought she was too young so I haven't made provisions for her near the ground. She laid her egss in a 3/4 enclosed nest box that is 3 feet from the ground. It has a 2 inch lpi across the front. The walk plank is about 6 inches wide. My question is...will she be able to get the babies down the plank to food or do I need to make a lower box? My first time at having a broody as I have just been incubating....sort of like the young mom that thinks her baby will always be a baby.
