I'm sorry, I know I probably came off that way and totally understand why you'd be upset or take it that way - i mean you should, i got kinda carried away.
But anyway, I totally understand being scared about losing them, sometimes you do just lose them, but you must be taking good care of them for them to all still be alive!!
Fortunately, it doesn't seem like you have too many bigger breeds besides the Orpington and RIR so they should be able to fit in it even longer but eventually I'd definitely try to give some to your friend.
I completely understand that logic, that's how my parents felt and thought it would be good forever. With that said, I hadn't realized 6 was the limit and had thought you were going to put all 10 in it. Although even with 6 it could eventually get tight but with the bantams and smaller breeds it could probably work
Apologies, I hadn't realized you only planned on 4 or 6, I guess I just assumed with the 6-9 bit you had planned on that many. I had also thought that you said you planned to free range but I may have read a different part. Anyhow, I think for only 4 you could definitely make it work if they have that run. Although I would definitely give them a lot of things to do to preveny boredom. And I know you've already invested a lot in it so I don't suppose it's possible to make the run a teeny bit bigger? They may get bored but with only 4 and if you give them a lot of stuff to do I think you could make it work.
Also, if you only plan on 4 and there's a limit of 6 and you do ever decide to build then you don't necessarily need a 4x8 thing like I'm building, 4x4 or 4x6 could work and be cheaper too.
But again, I think you could definitely make it work but I wouldn't recommend putting more than 4 in there and even that is a bit tight but I think it could work. Especially if you keep the smallest or the gentlest of the 10.
Sorry for being so mean before!!!
I think if you come up with plenty of things to keep them occupied it could work for 4. I guess I'm thinking from the perspective of my 8, it is definitely tight for that. I think 4 could definitely fit, at least on the roosts.
If you ever do decide to do something else maybe you could sell that one?
But I totally understand not wanting to waste the money and I think for 4 it will be okay if you can let them out sometimes or give them a ton to do. And maybe you could find some cheap or free stuff to make the run a littlr bigger? I know that with mine theoretically they have enough run space but it's boring space. Speaking of which, even if you can't make the run bigger it's the quality of the space that's important too. I mean, you could have an 8 foot eode, 50 or 60 foot long thing but if all it is is barren dirt/mud or shavings and nothing to do they will still be bored or maybe fight. In a smaller one you can provide a lot to do and they maybe won't notice.
