Broiler Breeds: These grandparent stock as you write do take years to build up, however, that process has already been happening as companies have committed and moved to the BCC, so additional growth in this will happen significantly faster than, when first developing these new breeds. Scaling up with demand is now more like a year to two now, as it is drawing from a larger base.
In terms of transitioning cage-free barns taking months and years to complete, vs a slaughter device for broilers being implemented significantly faster. I think this is also related to planning. To reduce down time, barn transitions can happen quickly, but a barn transition would likely not happen if new caged-hens had been just put into a system, rather they would wait for these birds to be slaughtered. But if they were near end of life, concievably a barn system transition could happen in the same or faster timeframe than a CAS is installed, based on a companies funding and planning.
I think it is also useful to consider the impact on welfare, when prioritising some of these interventions. Ie breed has a significantly larger impact on broilers than slaughter https://welfarefootprint.org/#
On the timelines of implementing cage-free commitments. It is true that many commitments made in the global north focussed on longer, and namely 2025 fulfilment dates. However, the implementation of many of these commitments started from the inception of their commitment in a phased approach. More recently, for example with Kewpie in Asia, smaller and shorter time milestones are being agreed upon, that perhaps better illustrates what change often looks like.
Overall, my personal perspective, and I do work on corporate commitments, they still seems like a good bet. Due to the combination of impact on animals in near/medium term, increasing the competence of campaigning organisations and embedding animal welfare policy within food companies.
A few points that might be helpful.
