Thank you all for the sweet replies!
@BantyChooks .....while this may exasperate the problem, you might enjoy knowing they're snuggle bugs who enjoy crawling up sleeves.
@HuffleClaw , they're doing fantastically!

I got individual pictures yesterday, and will be posting some soon.
Sadly, the smallest OEGB didn't make it.

Poor little thing never seemed 100%.
We're currently "cat sitting" my grandmother's two kitties, who aren't used to chicks, which is quite hilarious. I've caught the female several times sitting IN the brooder with the chicks/ducklings.

Even my own cats don't feel inclined to get
that up close and personal with young poultry.

Will snap a photo next time.

Not my favorite thing in the world (just on the off chance someone gets suffocated), so the babies might be getting covered up temporarily.
