So i separated a pair of my birds for breeding and i had a wooden nest box hanged to the cage from outside 3 weeks ago but the birds never went into it. So Then 3 days ago i put a small plastic one in the cage and she already is going in and out and got all the nesting out of it. it is impossible for me to reach it or check it without scaring them since it is in the cage and they keep throwing the top cover of it down. is there any way that i can change it back to the wooden big one that is easy to maintain from outside and make her go into it?
note: they were two pairs in a cage at first with these two boxes the wooden outside and the plastic inside. They went into both but the wooden very less than they did the plastic but i separated them to prevent fighting over the nest box.
