How long until i can let out my new cockatiels? its been 2 days now... They seem pretty chilled out today but still a very unsure of my hands they hiss at my hands... should i work on taming them first before letting them out and How adventurous are they when they come out for the first time... will i be able to get them back in. i dont think they would go any further than on the chair next to their cage or on top of it
