I have 8 hens. Some are 12 weeks and some are about 17. Lets start with the 12 weeks. I have 2 black sex links, 1 red sex link, and 2 white leghorns. Now with the 17 week....I have 1 easter egger, 1 delaware, 1 Rhode Island Red. When will they start laying? What will be the weekly rate of th hens? Thank you....in advance
