i have recently put 2 roos in with my girls. about 2 weeks ago to be exact. how long does it typically take to get fertile eggs once adding the roo? i know big daddy is doing his job but cant tell if hes finishing the job if you know what i mean and im sure you do. i have set some eggs but its been about 4 days now and no veining in any of them. its not looking as tho they are fertile. what do you say?
