Is it reasonable for the owner to give the key to others to open the door to raise chickens and want to charge property fees?

Unreasonable. The property privately gives the owner's door key to others to open the door to raise chickens, which is suspected of infringing the owner's private property rights and housing rights, and may also violate the property management regulations and relevant laws and regulations. Owners should also pay attention to protecting their rights and interests, promptly complain to the property company or relevant management departments, and find that the property company has violated the rules, and can safeguard their legitimate rights and interests through legal channels.
