Moving my chicks and bunnies outside- does this sound reasonable?

[MacMamaof4]

My four chicks are four weeks old today, and they've been with two female bunnies for the last two weeks. They're all friends and it's adorable, but I'm very ready for them to move out of my dining room.

I lowered the temp more quickly than recommended (keeping a close eye/ear on their behavior) so they've been living in our 69°house with no supplemental heat for four days now. In addition to that I've been letting them spend a few hours in the run every day for the past four days. Usually it's been in the low 60s but today it's only 50 and they're happily running around/sleeping/eating.

Starting on Monday our highs will be in the 70s and the lows will be in the 40s- do you think they'd be ready to move out then?

I think as long as they have a place to get out of the wind and rain they should be fine, but they might need a heat lamp if it gets too cold.

I don't want to put a heat lamp out there- I'd rather keep them in the house longer, but yes the entire run is covered and their coop is sheltered.
They were completely comfortable in 50° out there all day, so I'm hoping the low 40s won't be too much of a jump after four more days.

It won't, they will be fine.

They're old enough to go without heat in those temps.
