With Credit to MikeLanglois for spotting a mistake in the previous version I have updated the calculator which can be found here:

I have also replaced the link in the post below.

Hello everyone. Thank you for the feedback from everyone on the last post. I have made some fixes and improvements to the egg calculator for contracts.

New in this version:

• Correct calculations!!!
• An option to input data by selecting the units from a drop-down menu
• An ascii chicken

Please post here or message me if you find any issues or have ideas for how this can be better implemented for group contracts.

Thanks!
