this is my third generation with this method and I wouldn’t change a thing. The integration is completely stress free, once I’ve confirmed the chicks use the ramp to their side of the coop.
Folks have had success with this method. I have seen much bigger (wider, not taller) versions and others recommend obstacles / corner blockers etc. I haven’t had an issue there but they do have a lot of pluses.
These chicks have been doing this each day, 24-7, for a week and a half now, and another 5 days till they are with hens full time as a new batch of day old chicks arrives.
