A bit over 2 months ago i rescued a female cockatiel. She doesnt seem to have been touched alot and thats ok . i think i made a common error of placing a mirror in her cage..she loved it so much she layed a egg a few days later. I removed the mirror to add a new toy and a month later i changed it back to the mirror...then she layed a egg again today and sat on it most of the morning. The first one she ignored. She often leans towards me a coos and mumbles alot.and screeches when dad comes in the kitchen. I read egg laying is not good for her vitamin levels. Is it the mirror ?
