Unwanted situation by hatchery

[Sissy]

I would not treat them as yet wait
these may be fine.
But do keep them seperated. in the brooder.

Is it safe to drop the brooder temps as I should with the problem I have? I am also thinking if the chicks survive till the new ones arrive in 2 weeks I will build an new brooder. The old one I will burn. I am also going to disinfect the brooder, feeder and waterer today. This problem sure is a pain. Thank God I don't have a hundred.
