My only concern is they are unable to navigate the ramp and one of our goals in getting these is to hatch ducklings. Any ideas on how I can modify that ramp to make it work? As it is my husband added wood under the ladder to make it a ramp but they just tumble down it in the morning and stay outside all day, one of the girls has started laying in the coop and I'm concerned about how she can set if she can't get up and down the ramp. I'm going to try to out shelf liner on it today and see if it helps, but it's at such an angle for little ducks. Any ideas?
