As to the when do they start laying discussion: I think some of the timing is decided by where you live/your climate. My Poms started laying the end of November last year, but Kawonu's Poms didn't start till a couple months later. I am in SE Louisiana and he is in the Carolinas. I have spoken to a breeder in Iowa and his don't begin until late February to mid-March most years. So, I think your climate also plays a role in the timing.
This will be my second season with the Pomeranians and first with my pair of Toulouse. Last year, my original goose laid 51 eggs spanning 4 months. I was very pleased since I had read that they laid as few as 30 eggs per season.
Speaking of "the season" we are a bit more than half-way there for those of us in the deep south. Just four more months till the first of our girls start laying!
It looks like I will have 3 solid breeding pairs for this season out of the 14 Poms: My original pair, Caboosh (mine) and Wonky (from Kawonu), and Tucker (mine) and Derby (Kawonu).
I may have another two females from Kawonu's goslings that I can pair with Church and Shaazam my two remaining ganders; the girls beginning to really show their adult feathers and look to be well marked with a defined single lobes. Should that work out I will have 5 pairs to work with this year.
The second female hatched from my pair, Donut, has too much buff so will be put in the pet flock. I am going to try to breed her with a gander out of Kawonu's birds that doesn't have enough buff and see what I get. If nothing else, I can keep these goslings to cross with the toulouse for possible meat birds. I am still not sure we could ever kill and eat one of our geese though: They are just too sweet. So, if we can't bring ourselves to eat any of them, I will just sell those as farm geese locally.
I plan on hatching out at least 4 or 6 goslings from each of the breeders I keep prior to selling any eggs, except from my original pair: I am going to sell her eggs from the start once fertility is confirmed and only keep the strays that fall between orders.
Guess it is about time to start building the new goose barn before breeding season starts!
