New to the forum, so let me say "Howdy" from Texas. I have 18 chickens of mixed breed (mostly RRs and Barred Rocks). We decided to start raising our own, so I just got 2 roosters 3 days ago (one RR and one Barred Rock). The Red is mounting every hen in sight. Haven't seen the Rock do it yet, not allowed maybe? Idk My question is this: How long does it take for the eggs to become fertile? i.e. When can I start collecting them for the incubator? Thanks for your help.
