I have been given a birdcage that is 123cm high by about 51cm wide and 53cm deep. This is it on its back And the inside Need to patch up a little I will have it on it's side, like this But not sure this will be big enough to let chickens out, its about 13cm high The question I have is, will it be big enough to house 4 hens and a rooster? If so how many at most would you house in it? They will only sleep in it as I free range them and will let them out ever other day (have 2 roosters as of tomorrow). Thanks in advance.
