I gave her some banana and yolk which she had a bit of

Has the chick ever stood up or walked? Does it have splayed legs? Do you have a picture? Splayed leg is fixable if done quickly. Here is a good link if the chick has spraddle or splayed legs:

The chick never stood up, her legs were kept in a somewhat normal position and he toes normal
but unfortunately she passed away earlier today, she started breathing heavily and I think her organs just failed on her

Very sorry for your loss. Some chicks have problems internally we cannot see. Since she could not move around to get food and water on her own, it was just a matter of time.
