I have two, one year old silkie hens that have never used a ramp before...just a teeny tiny one that goes into a ground level coop. They seem to like being down low, and even lay their eggs on the floor of the coop instead of in the nesting boxes. I need to upgrade to a larger coop, and all I can find for purchase are coops with decent-sized ramps. Will they learn how to do it? If not, I can build my own ground level coop. They don’t have the huge crops, and can see just fine.
