I think you're right Rosemary, small flocks will diminish. For all those who have increased their production of POLs to supply pandemic demand, there will be a crash. It will suit large enterprises for there to be fewer small flocks around.
We had decided not to buy in any POLs again in the foreseeable future, although I would like to have maybe a min of 3 hens.
Meantime, I have been thinking how to provide an alternative winter housing system for the hens we do have rather than having them overwinter in the polytunnel, which is for veggies, including winter crops.
Our hens normally free range. They cover about 4 acres of the available ground, although they never cross the road thankfully. So I'm thinking of putting in permanent tall stobs (8' or more) around their henhouse, then wrapping round mesh for the winter, with some sort of flexible roofing - that's the hard part, extreme winds round here. It would all be removed in the summer, or perhaps it would be more permanent and we'd just leave the door open in summer. Does anyone have any better-thought-out plans for dual season poultry accommodation?
For us the geese are a bigger problem, being grazers. For their welfare, they need grass. If you cover grass year-round then it dies off, so roofing needs to be removable, perhaps like a swimming pool cover? Geese live a long time and ours are young, so they will not become fewer before we do!
What we need is for someone to design a good, functional system then we can all invest a bit and be set for the future.
