Three of my hens decided to go broody on me a few weeks ago. Two weeks ago, we found some duck eggs and decided to do the old egg switcharoo on them. One hen received all of the chicken eggs from two of the other hens. Those two hens each received 3 duck eggs each. The girl that got the chicken eggs had some issues with a silkie that kept trying to sit with her which caused some eggs to be kicked out and destroyed.
So she was temporarily banned from the coop. Three eggs hatched yesterday. I went into the coop this evening to check on the birds and I find one of the girls that had been sitting on duck eggs hanging out with mama. She was behaving as if the chicks were her own! Fluffing up, calling and clucking to the babies. As well as some weird beak rubbing on the ground. She is squatting side by side with mom. Cute and funny as heck since I never heard of a hen joining in on the mothering!
