l started out with warrens, lovely friendly birds and good layers. l have a mish mash of all sorts now but still some warrens. Just keep them clean and well fed, mine love treats like corn in the late afternoon, and they will love you forever. Mind you warrens are like food disposals units on legs, l dont feed any meat products to mine. Examine them and their perches for mites now and then to keep them mite free and you cant go wrong. Good luck and enjoy.
