Hello, We know very little about chickens in general but have been reading and trying to soak in so much on this site! We had a nice year with our 5 hens. We love getting the fresh eggs daily and our small children couldn't get enough of carrying one of our two silkies around in a basket. We couldn't figure out why one silkie didn't get along with the other chickens until the day it started crowing! Jump to about 10 weeks ago when our silkie hen hatched 4 eggs that belonged to one of the RIR (so RIR x w/ Silkie). Everyone excpet my husband was very excited. Now it is obvious even to me that 3 out of the 4 are boys!! I'm so sad about that! Our silkie roo has found a new home as he was always very aggressive (which from what I gather is out of character) and we also don't want more chickens. Here are my questions. 1) Is there any advantage to having roosters? 2) They are free range during the day and sleep in a secure pen with our goats at night, can the roos sleep with the hens?? 3) Are most roosters aggressive? Two of my little ones aren't big animal people and are therefore easily intimidated, which is a visious circle. 4) Until reading this site, I always thought "you" only ate non fertilized eggs. We collect our eggs daily but obviously an unknown number would be fertilized if we keep the roos. I need more convincing that it's really o.k. OR the reasons why some people don't. Thanks so much for your time!
