Not sure if it will keep her from egg-laying. There is much advice here for that. Cockatiels do like toys and should have a variety of them. I find my tiels mostly like toys they can shred - you can put a variety of parts together on a bird skewer...mine like balsa, palm, finger traps, cork, mahogany slices and pods, yucca, seagrass. Seven weeks sounds young for a tiel to be weaned...I thought they were a little older when they wean...I brought home 2 babies when they were just about 3 months old...and had toys for them in their cage. They will sometimes play with bells and some toys from Avain Stainless - but they really like their shreddables.
