Don't know why this is happening

[moodles49]

Hi.
I am bit concerned about one of my 2 budgies. I bought new food recently & the one is fine but the other has started a little squeak sometimes when she breaths, but apart from that she is fine .... eating, drinking , playing etc. I find it strange that if it's the food it's only affected one , but they are sisters?
Can anyone advise me Please?
Thanks SO much x

I'm sorry one of your birds is giving you cause for concern.

I'm sure someone will be along to help.

I would doubt if it has anything to do with the food tbh, a noise or click when breathing can be a symptom of different things, respiratory, thyroid, crop mites or problems.
I would advise a vet visit.

Too many problems present with the same symptoms to be remotely diagnosed; I agree with skysmum, a vet visit would be best. Not all birds have the same level of immunities as another, just as humans don’t; something that one may shrug off as nothing can be a killer for another.
