I have a few questions for the experienced chicken keepers here. My little frizzle Cochin hen went broody 3 weeks ago, so I ordered some fertile eggs. I received 6 eggs, and gave her 2, and put 4 in an incubator. I candled the eggs today (14 days), and the 4 in the incubator are looking good. (Well, 2 are black copper Marans, so it's pretty hard to see, but as far as I can tell, look good.) One of the two under the hen looks good (now, this is my first time candling eggs so I'm hopeful but by no means certain), and the other I'm not so sure of... First question: if an egg is going to go rotten and explode, will I be able to smell it first? They all smell fine, but I'm not sure one of the ones under the hen is developing. Second question: Even though she's only had two eggs under her, could I give her the chicks from the incubator eggs? If I sneak them under her backwards? Or will she "know" that she's only supposed to have 2 chicks tops? Next question: Now my other bantam Cochin hen has gone broody. Could I try giving her chicks, even though she won't have been broody for the full 21 days ahead of them hatching? Or will she also know that something funky is up? Can't wait for you all to weigh in!
