I've got two pekins and four rouens right now that were born in April. I know I have at least two (possibly three) females out of the bunch. How old are they when they start to lay? I know you're supposed to start feeding layer feed so I wanted to make sure I was feeding them that when I'm supposed to. Also, if you want to sell the eggs or the hens don't go broody, what do you do with them? Thanks!
