okay I'm new to the whole egg laying thing and I love my hens so much, I bought then as day olds and hand raised then to be sweet and loving, they are 18 weeks old and my biggest hen has been laying every other day, I have gotten 2 eggs for her, how long does it typically take for them to lay an egg, today is the first day I have seen her in the nesting bowl and she's been in there for 30 minutes and I'm getting concerned as its hot and she's panting, I took her some Apple Sauce out which she greatly enjoyed, I don't want to bother her but I'm a worried mommy...
