Last year year all 6 hatched cygnets were killed. I think by snakes. I put repellant out every other day prior to hatching. I am considering taking the hatched cygnets this year and raising them in a controlled pinned area without the parents. Please comnent on this. Is it ok and if so how do I care for them. Water food ant advice is appreciated. Out of trying for 5 years I have only been able to have 4 cynets that survived out of over 30 eggs layed. Thanks in advance. Ronny from just South of Dallas
