Starting this so GOG Everdream Valley players have access to bug lists for the GOG-specific installers and dev contact info posted over on Steam. The devs have tried to test the updates out over at Steam first and address issues before posting the GOG versions, but bugs still get thru.

DEV CONTACT INFO: If you do not use their Discord servers or social media - -----

KNOWN BUGS (at the time of posting):

A critical Save Game Bug is causing crashes. It is being investigated and players affected are being urged to send save games to the support contact above. So far it seems to be linked to sleeping in the tent or treehouse.

The 3.703.1346 Update Chicken Coop Bug: This update introduces a bug which nullifies the Chicken Coop - it causes the Chicken Coop to not register as being there for the chickens and chicken perches, causing your chickens to return to wild. Picking up and replacing the Coop or even replacing it with a new one does not fix it. Caution against applying this update until this is fixed if you want to keep chickens.
Update - Devs are now asking for GOG players to send screenshots and save games displaying the ! above the chicken perches to the support email above.

Chicken Coop Bug Update:
The devs are asking for screenshots and save files displaying the Chicken Coop bug - where the chicken perches have the exclamation ! over them. They are asking for these to be sent as specified in the OP: ----- You are welcome! :)
Now can anyone tell me how to take a screenshot in this game? My usual prt sc methods aren't working, or else it's being stored somewhere I'm not finding.

I sent you a private message. ;) But now I've decided to post it here, just in case someone else might have a similar question.

I use Galaxy to launch Everdream and it's overlay menu comes with a screenshot feature. Otherwise, any other freeware screen capture tool should do the trick. I have tested it using the open-source app called Greenshot, which works on some games and not with others.

In order for Greenshot to "see" the game, you'll need to run Everdream in windowed mode or borderless windowed mode (in the game menu, go to settings, then graphics, then display... avoid full-screen mode if using Greenshot, as it won't "see" the game). Whenever you hit the PntScrn button, a screen capture is saved in the following directory: C:\Documents\Pictures\Greenshots

Hope this helps! :)

It definitely helps! Thanks! :)

If others can also send in save files of the Chicken Coop bug after patching or installing the 3.703.1346 Update, the dev team would appreciate it. I would suggest backing up your save game files first so you can return to the unbugged saves afterwards (by rolling back in Galaxy or using backed up offline installers) while the devs work on a fix.
