I can only suggest getting yourself a legal expense insurance. It may not be to obvious, but there will be day, where you get a customer that makes a very sweet deal and later won't pay you. It devinetively is good, if you don't have to take the costs of it going to court.
Idk about the EU(there have been cases that were exactly this, an example would be Article 13), but I can say to you, that this devinetively happens in Germany. Our conservatives party wants to pass a law, that would track and save all your online activity(Vorratsdatenspeicherung/ data preservation) to fight "paedophiles and terrorists" they bring it up once in a while, even tho, our federal court already said, that its illegal.
The hens are bred for laying as much eggs as possible, on the cost of meat production. this means, that it isn't profitable to raise them, just to get some meat, when you can raise other chicken breads to get twice the amount of meat.
AS far AS i know, there are experiments with identifying the gender in the egg, but it isn't practically usable on a big scale. I might be wrong, would love if someone knew more about this.
