Well my Muscovy girls have been laying lots of eggs but noone wants to brood yet till yesterday, iwent into the duck house and my little cochin bantam was sitting on the eggs so i thought she is probably laying her egg in the pile they do that sometimes, well 2 hrs later she was still there so I lifted her up no chicken egg but she was planted on the duck eggs, last night I had to take her out of there to put up the ducks and she pitched a fit, this morning she was back on the eggs as soon as the door was open. So I went and took all but 4 eggs out from under her, she is bantam after all and thats alot of egg under her, so now I have a question since i have never let a chicken sit on duck eggs or vise versa, can she sit for 35 days? that is a long time for a chicken to sit on eggs. She is a great broody and mama I haven't got any worries there but I don't want her to sit and give up when it takes so long. Has anyone any experience with this? if so please let me know what you think. Thanks..
