Got a Sportsman 1502 for Christmas and....
I put a dark cockerel over partridge pullets this spring. Set 21 eggs, 16 were fertile, 14 hatched (guessing 6 pullets, 8 cockerels - 3 weeks old). The 5 that were not fertile I suspect came from the same pullet. She would tuck her tail every time he mounted her, so I don't think anything was happening there. She's since been rehomed.
I also put a dark cockerel over dark pullets, but I haven't seen him do the dirty yet and haven't checked any of those eggs for fertility. He's really nice and big (from Diana Delaney) so I hope that he starts getting active before fall...LOL.
I have a broody hen that I've put 7 dark x partridge eggs (all developing) under and 3 darks that were developing in the incubator. Story on the darks in a minute. Due on Saturday.
I bought some eggs from Florida, they sent 18. Of the 18, 4 started. 3 were developing so I put them under the broody...I can explain in a PM if you really want to know.
Got some partridge eggs from a really nice line in Ohio, they are on day 8. Candled yesterday, 10/12 started. Fingers crossed that I'll get a good hatch.
And....not hatching related but got some really nice partridge chicks shipped to me from Michigan.
After this last batch of partridge eggs, the incubator is getting shut down for a while. I'm overloaded with chicks right now and need to let some of them grow up so that I can see what I've got to work with.
