I have 6 Hy-line hens, 2 bantams, and 1 Barbrock and a Rhode island red rooster. I let them out everyday so they are freerange. we feed them, table scraps, laying mash and maize pellets. if I wanted would the hyline hens and the rhode island rooster make good laying chicks? and how would I check if the eggs are fertilized Thanks in advance Elsy
