I didn´t said the ground need to be natural.
I just said it should be flat so all the foot get pressure and not few spots like on wire.
Sand is alot more natural than wire if you want to look at it that way.
In my outside cage they got grass growing in where they make tunnels and are able to...
If you use sand you shouldn´t get any problem with things getting stuck on their feet. My quails in the outdoor cage got no problem with their feet and no problems with the young quails that walk on newspaper or towels too.
Well atleast in my country it´s illegal with wirefloors and i don´t belive it´s good for the quails to have to walk on wire.
I would say that if you really care about your birds you let them walk on a real ground where the whole foot take the pressure.
Letting them walk on wire is bad for their feet and cruel to any animal. I had sand in the cage and it was easy to clean and didn´t need to clean that often.
But only the brown chicken will be brown as adult i think. And alot baby chickens look the same so i guess it´s easier to see once they are grown up.
Åsbos and leghorns maybe look alike each other
Depends on what turner you use. Got one that tips over you can put the round end up but if you got one that slides side to side the eggs are supposed to lay down. I always let the eggs lay down sinse it´s the normal way they are supposed to be.
They seems fine. Letting eggs touch each other is no problem as long as they aren´t on top of each other.
But can be a problem if you plan to let them hatch in there sinse the chick wont get any room.
