That's not to much of a temp difference, no need for acclimation.YEah the stall is where I brood chicks in the summer. 4 solid wood walls, hardware cloth across the top and window/door.
They are 4 weeks old. Almost fully feathered, but not quite.
Currently, they are in the basement, but it's not a finished basement and it gets down to 40-50 depending on how cold it is outside. It's unseasonably warm outside for this time of year, that's why I wanted to get them outside sooner lol I can easily move their MHP outside too, just didn't know if it was necessary.
If the MHP is easy to move, and they still fit under it, that would be quicker than acclimating to the huddle box....go for it.
