Bad smell really tells something. The moment when I go inside a farm the first thing I sensed before I can see is smell. The stronger the smell the more birds and nests will be in the farm.
Successful farms have smell that are so bad that you have to wear mask. The mask is good to protect you from not only smell but also parasites.
The birds get use to it and they seemed to like it. The smellier one has more birds. Imagine if a farm that is more than 3 years and the moment you enter you smell nothing, what's happens?The answer is "fail".
(successful farm with inches of thickness of shit. Like walking on a sponge.)
So smell is very important that is why many new farm's owners tried to imitate the condition of old farm by putting bags of birds shit in their farm. But often the smell generated by these bags shit are not Strong enough. Therefore the special Aroma is needed ( Love Potion). I don't put birds shit in my new farms. I only spray Love potion once a month. The smell is good enough to attract many birds to my new farms.
Given all conditions of farms ( new farm) are perfect plus good application of Love potion, there will be patches of dropping within the first few weeks.
( when u see this look above they will be nests on top)
The more patches of dropping in your farm the better this indicates many birds had visited your farm and some had stayed.
It is not impossible to see many dropping the first few days. As for my new farm there is about 12-16 patches of birds dropping on each floor the first week after the farm opened, given the condition where it was not located in a prime bird zone area I am satisfied.
So SHIT Means Good , Not Shit you're in troble..ha..ha..
Good Luck!
