How many strikes ...

... Before she's out?

What criteria do folks use to decide when to cull a female from breeding due to low fertility?

I have a nice female normal that I've tried breeding two years in a row now -- multiple confirmed locks to a proven fertile male -- and she hasn't laid either year.

Now, if she were, say, a coral glow, I would probably give her every season until forever to get her act together because her color gene would be valuable enough to overlook the poor breeding record. This is a normal, though, and I have extremely strict standards for normals (must eat F/T like a retic, must have an exceptional pattern and color, and must be highly fertile!)

I'm thinking no more than two strikes for a normal, maybe three for a more common morph like a pastel or spider, and as many as she needs for something more genetically valuable ... What are others' cull criteria for poor-breeder females?

Wait...you're going to kill her because she doesn't lay? IMO, that's absolutely not an option. Give her to someone as a pet, don't kill her because she hasn't breed for two years.

Other than that, there are plenty of people that have waited 2-3 years for a female to finally lay. It just depends on how long you are willing to wait. I can understand not wanting to keep a female around that hasn't bred, but not culling her. Perhaps you mean you are going to give/sell her to someone else? When I think of culling a BP, to me that means they are going in the freezer.

I personally would try again..... It can take time for a female to really be ready.....

LOL, I doubt Serpent is meaning to kill, yes cull generally means that but I think they mean to remove from the breeding program, not literally kill the snake :O

I was thinking after I wrote that message that he can't mean cull like I'm thinking... Thinning the herd, but not with guns, or freezers in this case. Ok :gj: :P

How old is she? It's not that uncommon for some girls to need 4 or 5 years before they'll lay their first clutch.

Hi,

Was it the same male both seasons?

If not I would double check by outting her with a different male - it may just be that specific pairing that has problems not either parent?

You could also be missing her developmental period. I know of someone who tried to breed a female multiple times with no luck. Once he started ultrasounding he realized she started developing way earlier than his breeding season started and absorbed the follicles before she was able to be bred. Once he realized her developmental time was so much earlier he started pairing her and gets viable clutches from her every year. I know it would be more trouble to go out and buy an ultrasound to figure out a normal but its definitely a possibility that you're just missing her time instead of her fitting into your time.

Luke makes a great point. BPs tend to go when they're ready, not just when we tell them to.

And to others, if you look up the definition of cull, it's not just killing an animal. It is also meant as removing animals from breeding.

If it were me, though, with a normal not producing for me 2 years in a row, I'd send her packing, as I have limited space. I'd rather a morph take her place in my small rack. But that's just me...

What if the problem wasn't the fact that she was't laying eggs. What if she slugs out. How many pairings would you put up with?
