i have a little dilemma here, it seems the brooder my 4 x 4 week old poults are in is too low, they keep scraping their heads on the mesh(!) so i need to quickly move them into something else. now i have an old rabbit cage, a lot taller than the brooder they sit in now, the same length but not so wide. will this be ok for a while, while i make something else? (it is 1mx50cmx50cm) or is it likely they will start feather plucking/fighting etc?
