Hi,

A friend is going to lend us her plymouth rock hens for our rooster. She wants to get a few plymouth rock x australorp chicks out of them before sending them over however. We were wondering how long it would be until the hens had gotten the australorp sperm out of the system before we tried setting eggs from our rooster. Hope this makes sense. Have been told that the eggs from a particular rooster can be fertilized for a week or two after one mating but thought someone on here would probably have a better idea.

Thanks very much

there have been a few threads on this subject, people have said they have had chicks from eggs up to 2 weeks after mating :shock: basically after 4 days the fertility decreases, old timers who single mate say they need to be mated every 3 days to ensure fertility---the majority of people tend to work on a week before they start setting eggs when a new roo is introduced, with some people opting for 10 days, to be sure :) cheers pam

Ill just asking something about this, say you have a rooster with 2 of your hens and then you swap over the roosters, this could be just wrong or if i am thinking right i may have it correct, wouldn't you have the Sex cells? from the rooster 1 and then when you take rooster 1 away from the hens and put in rooster 2 and they mate wont there be both Roosters Sex cells in there?? That would only work if they both have had a successful mating but would it or not. sorry Cookienpeep for Hijacking your thread with that.

for that week to ten days after the swap of the roosters the eggs may have been fertilised by either roos sperm, so the chicks hatched from those eggs you have no idea which roo is actually the father----which is why people wait 7-10 days after a roo is introduced to be sure of the parentage.

sperm looses motility with age so after 3 days the first roos sperm will be less vigorous and the second roos sperm being fresh will be most likely to be the one fertilizing the eggs, but you can't know :? cheers pam
