I have a flock of about 30 chickens with 3 rooysters and 3 ducks on the side. Well my ducks started laying eggs long story short one of my older hens was broody and would sit on the duck eggs right after being laid. Now I have about 12 eggs at different stages of development. Well I let her sit the eggs and about 2 weeks ago an egg hatched no surprise a chicken had lad an egg in with my duck eggs. We moved momma, chick and eggs into a dog create with food and water. All was well until yesterday when one of the duck eggs hatched. All seemed fine I got home today after work my husband reported that when ever heard would look in on ducky he would find momma chicken had pushed out from the eggs and it was shivering in the cold. Well then Ifound she had pecked at ducky right behind the head at the neck and now there is a soar there. Of course I took momma out to the coop and set up a brooder with heat lamp and my husband said take the eggs in there with ducky and chick. I have it nice and warm at about 98 to 99 with a wet sponge for humidity and wood shavings. Should I go buy an incubator tomorrow or take the eggs out to another broody hen? And put triple antibiotic on it?
