At a loss with what to try next....

I have had the 2 bantams since day old but they were in the brooder in the house, the 3 barred rocks I just got a week or so ago and put them outside, with heat lamp, just a waiting game I guess...

The barred rocks probably brought the problem with them.

Call the hatchery or feed store and get a refund or replacements

You should always quarantine newcomers!!
The rule is the rule of "minimum 40:40"
Minimum of 40 days of quarantines
And minimum of 40 feet of distance between the newcomers and your flock.

They all seem to be sneezing less, no bubbles in the eyes. So I'm hoping whatever it was is passing ....I did put a humidifier with eucalyptus oil in it for 2 nights....I don't know what helped but they seem to be getting through it
