Sneezing for a month but otherwise fine 🤧

[0range]

I have 2 five week old chicks that have been sneezing for about a month. They sneeze every few seconds no matter where they are or what they're doing. No eye issues or anything. They seem lively and totally normal apart from the sneezing.

Any ideas or advice would be most appreciated! Thank you

Can you get a video of them? Upload to youtube and provide a link.

If they are eating/drinking/active and have no other symptoms like runny mucous from the nostrils, watery or bubbly eyes, facial swelling, etc. then I would just observe.

Perhaps something in their environment is an irritation - dusty feed or bedding. Could they be sneezing right after the eat/drink (have some food/water or dirt in their nostrils)?
