Mamma might be sick, how do I treat?

Black Betty with her 7 day old chicks. My first time having Mamma do all the work!
She was breathing a little heavy yesterday and sneezing today. Babies are fine so far.
how do I treat them? Tiaguard in the water? Is that safe for such little peeps?

What are mammas symptoms? Is it respiratory? Wheeze, sneeze, mucus? Or is she sleepy lethargic and slow? Makes a difference on treatment.

Yesterday I could really hear her breathing. Today, she was sneezing. It got chilly and wondered if she was struggling to stay warm. I turned on the brooderabd put a blanket over the dog crate. She made a nest right next to the heater.
