We have a broody Bantam Cochin that we bought some fertilized eggs for. They are standard/large eggs. There are 7 of them. It looks like she is sitting on all of them, but I see the edge of on sticking out. She has done a good job getting them all tucked in in a very short time. Will she eventually get the rest of that one under her all the way. Is it okay? Should we /can we change the bedding from shavings to straw? Sorry for all the questions, we are first timers with hatching.
