DISCLAIMER: this could be in the totally wrong section, but it does have something to do with genetics so i figured it somewhat belonged. BACK STORY: Okay, so i have a flock of eleven chickens. i have 1 cockerel, and 10 pullets. my 18th birthday just passed this saturday, and i recieved an incubator, so im going to breed my birds. my flock is nearly 27 weeks old at this point. ANYWAY, my chickens are not free range, and i get roughly 7 eggs per day. 6 brown, one white. but unfortunately, things arent just white and brown. i get 3 light brown eggs, 2 dark brown eggs, and a strange tan colored egg along with my white egg every day. I have two rhode island reds, two Isa browns, one barred plymouth rock, one Buff orpington, one (i believe california grey) leghorn, one brahama, and three easter eggers. my only cockerel is an EE. as of right now, my two EE pullets arent laying, and aparently neither is one other bird. I'm fairly sure that the brahma is laying the beige/tan egg, and the white egg is definately from the leghorn, but in order to find out which shade of brown eggs are coming from which birds, i have devised an experiment. EXPERIMENT: I'm going to seperate pairs of birds into cages equipped with food, water and e nesting box. the pairs are as follows, The two Rhode Island reds in one, the two Isa browns in the second, the brahma and the leghorn in the third, the Plymouth rock, my cockerel (i'll tell you why him too later) and one of the non-laying EE's in the fourth, and the Buff orpington and the remaining EE in the fifth. because of the way i set it up, im sure that i'll be able to nearly precisely determine which eggs are being laid by which pullet. I post this becasue im curious to know if there is a flaw in this plan. my mom told me that it might not work because the girls will be too stressed out to lay, i'd figure you guys would know better than either me or her. they would be in these cages for no more than 8 hours. roughly from 7 am to 3 pm. GENETICS QUESTION: okay. so saying i theoretically find out who is laying which egg, i want more barred chickens more than anything, so is it possible, with the genetics from my plymouth rock and my EE ( he is mostly black, but with quite a bit of white on his head [like a mane] and some dark read and yellowish white on his back and tail, looking like his back is on fire) to have a barred chicken that carries the genes for blue eggs? or more simply, would i, COULD i, get barred chicks from this pairing? or do i need to find a new roo? and while im at it, does anyone have any idea about what the cross between Eagle and one of the RIR's could look like? all of your help and feedback is much appreciated.
