では at the end of a sentence

[Takoyaki]

I have been studying conjugations of だ lately and from what I understand では is a 未然形　which means it refers to things that have not happened, such as with ない or guesses. Of course the below sentence would fall under something that actually has not happened yet, I am wondering what kind of connotation this has over just using だ or　です here.

It's all right if you only feed them a little bit.
少しくらいエサを与えてもいいのでは。

I have been trying to find more examples that don't confuse me further but it's been tough keeping it simple.

There's an understood ないか or ないかな or something like that at the end of the sentence. So it's 少しくらいえさを与えてもいいんじゃないか in more formal or feminine style. It's not something you'll probably run into that often.

Ah, yes that fits better. Thanks a million!
