Question

Hello Rabbi,
A. Has the Rabbi heard the arguments that most of the poultry marketed today (broiler chicken, I think) comes from mixing several species of birds (some with an established tradition and some without), and therefore one should not eat poultry today? They claim in support of their argument that there are several changes in chickens that could indicate and point to this. Has the Rabbi heard of this or something like it? If so, is there an answer? Are they mistaken on the factual side? I simply don’t understand this…
B. I saw somewhere that the Rabbi says we have a historical right to the Land of Israel because we were the first ones here (and still exist today…). Two questions: 1. How does the Rabbi know that we were the first? I saw an argument by Palestinians that they were here before us, that they are Canaanites, etc. Seemingly this is a historical dispute—how does the Rabbi know how to decide? 2. Suppose it is ours—why are all the sales that took place here not valid? A Jew sold to so-and-so who sold to so-and-so who sold to a Palestinian, and today it belongs to him—how do we have a right to that land?a0
C. Does the Rabbi have, or has the Rabbi spoken somewhere, about a solution to the Israeli-Palestinian conflict? Two states? Expulsion? No solution?a0
Thanks in advance.a0
