My worst temptation is when one of my girls gets broody. I want them to have something to hatch. I mean, can you imagine sitting on a clutch of eggs, or a pencil, or a small rock, or a piece of wood (Silkies are not choosey) for 3 weeks and having nothing to show for it? 23.5 hours a day/7 days a week.
If I have a rooster, I gather eggs that I know are purebred. If I don't have a rooster, I either buy fertile eggs from a local breeder ($3/dozen!) or.....*drum roll*
I go to the feed store.
I brought home turkey chicks for my Silkie bantams once. They raised those turkeys up so well. I could write a book about the drama. Turkeys could not figure out which white Silkie was their mom and if they went to the wrong one, BAM! Then Mom comes over and BAM on the other Mom for the BAM on her chick...and the cycle continued...
I'll do turkeys for Thanksgiving this year and yes, my Silkies will raise them for me. Best thing for turkeys because the chickens show them how to go outside and how to go inside. Without Mom, those turkeys would die of thirst because the water bucket is on the outside of the coop, in the run. Right there, through that open door..... just through the door.
