don't worry about the background, it takes time and patience to get the bird looking and standing right. Believe me there are many pictures taken by pros that don't get published!
All editing programmes are good but when taking the birds they need to be as near to how you want them from the outset.
The first pic, head turned, flights not sitting straight, tail split.
When the pic is edited these are things near impossible to correct.
Was a Parts manager for Mercedes, Aftersales manager for Nissan, Suzuki & Hyundai dealer, retired again, now self employed Driving instructor and Own an marketing business.
It all depends on the loft set up!
If open door then as soon as they are weaned, know where the food/water is and know what shaking the tin means then open the door and let them walk out.
If they are in an aviary or have a flight where they can have a good look out then there is no need to get them out as soon.
