Hello. I have been trying to research this all weekend and haven't found much. I thought someone on here may be able to help me. My son has a flock - 2 White Leghorn roosters and a mix of Ameraucanas, Production Reds, Rhode Island Reds and Red Stars. We are trying to hatch some of the eggs, and I am trying to find out what to expect. I believe the White Leghorn x Ameraucanas will produce a chicken that lays blue or green eggs and lays more than a typical Ameraucana but less than a leghorn. Does this sound right? Any idea on how to sex? The White Leghorn x Production Reds or Rhode Island Reds - I haven't found anything except for the reverse of this situation. I found one study from 1930. Any idea what these will look like? How to sex? I think they will lay lighter brown eggs and be pretty good layers... The third scenario - we bought from a local farmer several of what he called red stars. These are smaller than our other birds but lay consistently. I also cannot find any information about the White leghorn x Red Star. Would this pretty much be the same as the RIR mix - probably laying lighter brown eggs and laying pretty well? Ideas on how to sex? Any information anyone could offer would be greatly appreciated. I have about a week until these hatch. My son wants to sell some, as he is running this like a little business. (He is 10, and he loves his chickens. He is the President of the 4H Vet Science Program. And, yes, I am proud. Ha. ) I want him to be able to talk to people about exactly what they are getting. Again any info would be greatly appreciated. Thank you!!
