My hens (9 total) only lay on one single nest. There are 4 others nests which looks similar or even better than that 1 they pick to lay their eggs. No big problem with that but 3 days ago one of the hens became broody and 2 days ago another one became broody and yesterday a thrid one also became broody. Yea there are three broody hens on the same nest. All the eggs others hens lay are there also (I assume something like 18 eggs). I don't know what to do... Any suggestions? Thanks.
