we have 2 female and 1 male finch and 2 nesting baskets, I gave him the artificial nesting material and he put it all in one of the nesting boxes, and then I gave them some alphalfa sprouts for some greens in there diet, and he put that in there too, he tales pieces of the paper on the bottom of the cage and puts all them in the nest. Is this normal or should i take everything that she can put into her nest out? The other question that i have is all 3 zebra finches sleep in the same nest every night together. Is this normal?
