i put 6 eggs in my broody hen but after one day she laid 2 more eggs and start incubation total 8 eggs. she cannot covered all eggs completely. i can see always that 2 eggs must be half opened. and she never leave the nest box she eat only one time and when i go near to the nest she ran and sit on eggs.and she often change the location of every egg. is everything alright?
sorry for bad english.
