Hi, iv got 30 quails that was kept in mesh cages for about 3 months with plenty of light and was getting at least 2 dozen eggs a day but they seemed over crowded and kept catching there nails, so 3 days ago I had a new pen built for them double the size they was in before and I have put down sawdust which they seemed to love but I only got half a dozen eggs yesterday and 3 today what have I done wrong? Is sawdust no good? Any help much appreciated many thanks
