It does really! The explanation is that I'm growing tomatos from seeds. I sowed them few weeks ago and they now needed more space.
To really get them in good start with the growth I added one tablespoon of organic tomato feed per pot.
The feed did not smell like anything when it was still dry, but after I watered the plants the chicken poop smell was obvious. The tomato plants are now in the office and so is the smell too. Bit of a farm smell inside, nice.
