hello im pretty new to this whole game thing but do know enough. i have 9 villager eggs but i can get they to hatch when i right click. Do i have to have anything built special for them. do houses need to be made out of certain material or can it be anything ? i have my recidence build 64x64 built up about 20 blocks and down about 10 and doors in the ground level in town but they won't hatch. Thank you if you could help me.
