Hi, I currently have a broody silkie who is sitting on two red cochin eggs. I collected them from a friend who's hen had been sitting on them for 'a few days' and I set them under her on August 28 (15 days ago). I went to our cottage for a week and had a friend looking afer my chickens. During that week a rat decided to move into our barn. My friend met with the rat early one morning and he was having a 'wrestle' with the broody hen. She scared away the rat however the two eggs had fallen off the bale of hay the hen was setting on. The eggs fell approximately 3 feet onto hay below. This occured when they had been under her approximately 5 days. The eggs were still warm and my friend put them right back under the hen. I'm concerned the shaking may have killed the chicks. The eggs are a dark brown. I've researched a lot about candling but just can't get it. The hen is now in a rodent proof cage (plus we killed the rat) and when she was off the nest yesterday grabbing something to eat, I gently picked up the eggs and examined them. They don't smell but I felt a 'swishing' feeling as if there was liquid in them. I would have thought by this stage (as least 15 days if not more) then the egg would have been mostly chick. Day 21 is Thursday, Sept. 17 but I'm concerned that if they are toast then I need to source out a couple of day old chicks to slip under her. She has been a dedicated broody and is loosing weight and I don't want to set another load of eggs under her. Any other way, apart from candling, for me to know if they are viable? Please help, thanks.
