"The other hens make many eggs per day."
Translation:Celelalte găini fac multe ouă pe zi.
Hello there! Yes, you're perectly right: whereas "acesta/acest" and "acela/acel" change their form depending on their position (after or before the noun), "celălalt" remains the same, irrespective of the position. Thus: "băiatul acela" = "acel băiat" = "that boy" and "băiatul celălalt" = "celălalt băiat" = the other boy. I hope that my answer will help you! Feel free to ask questions whenever you want!
