Breeding european goldfinch under controlled environment - light management

In order to be able to breed european goldfinch in captivity, it is necessary to have an aviary room in optimal conditions (temperature, humidity, light, air).

Sometimes it is not possible, for example in case of dark local. In this case It would be better not start breeding, unless they do not resort to artificial light.

Artificial light, in my view, has at least three advantages
- Increase period of breeding up to four months
- Control almost perfectly when moult starts
- Bring forward by one month the period of reproduction

We recommend using a neon 120cm each 5 mt square, and as many incandescent light bulbs to simulate sunrise and sunset.

A good light programmer needed!
In the table below is shown how to program the light to start playing in mid-April and end in mid-July.





I hope this topic can help you to manage better your artificial light and have a lot of goldfinch babies!

Have a nice day,
Nick
