hello I am new to raising chickens . I bought my first chickens today . they are leghorns I got six hens 7 weeks old . I need any and all advice on everything ! I want to raise my own eggs and wanted to have some chicks later on but I was told they don't lay on their eggs . so how can I get chicks from my chickens ? I don't want to have to buy more and an incubator is expensive .
