Hey
@Ssekaku samuel, that is a great question!
Someone has asked a question before about eggs not hatching well, so perhaps you can check out the link below!
The chicken I have always hatch two to four chicks from a batch of ten to twelve eggs. What am I doing wrong or what should I improve on?

To better answer your question can you further explain when you said "they lay eggs in one place"? Do you mean all of your birds are laying in one nest?
