While I have been taking pictures forever, I just started trying my luck with micro stock.  A bit of background:  I work as a software designer in IT but live on a hobby farm in Wisconsin.  Much of what I photo is related to our farm and surrounding areas.  (photograph what you know, right?) 

I would like to get some constructive feedback from folks here. 

This is just one sample. 

Thank you for your feedback.  Yes, I assumed eggs were common.  I have a couple of photos on my hens and goats out there, too. 

I need to train my goats to sit still.  Right now every time I put my camera to my face, they come right up to the lens thinking its a snack.  (why else would our human put something up to her face, if not to eat it?)  Blurry goat nose photos won't sell!

Good image. Low color and constrast.

It's not only that eggs are common, but why would they be on a cut treetrunk?
Look at what other people have done with eggs, and see if you can think of anything sensible* which hasn't been done before.
*but WDIK? I remember years ago noticing one particular photo coming through on iS and thinking WOE (to be polite), and a couple of months later I actually saw that same pic used on a poster fairly near me - one of the extremely few times I happened to stumble upon someone else's pic 'out in the wild'.
You can never really tell what will sell. 

PrincessFerf you need to think outside the box.

Everyone does eggs it'll never sell.

Why not have a hen on her nest with her chicks tucked up?

Or some other aspect of farm life that hasn't been done to death.

Do some research by looking at what photos are already out there?

Talking of which how about a big meat cleaver stuck in the block with a chicken staring at it?

I'm not kidding you never know it might sell

I shoot what I like to shoot, I always have. No point doing it otherwise. I did one shoot, because I wanted to, and afterward discovered there are literally thousands of shots identical to what I did. I got dejected and almost trashed the whole bunch. Instead I said f@#k it, I'll upload anyway.

The best selling of that shoot just crossed $500 and the whole set has brought in about $850-$900.

I don't tell people to shoot what they think will sell. You might as well get a job selling paperclips. Shoot what you enjoy. Be creative and do it well but enjoy it.
