auntie, so glad it wasn't a hawk! I have that problem around here too. Thought one was after our chickens last week, watched my golden retriever that was out there, he kept looking back towards his kennel. I thought, on man, that hawk has it back by the corner of the fence..no..the chicken had flown over the dogs fence, and was probably chased by my Toby, and ended up in the kennel. Wasn't hurt on the body, but it had hurt it's comb while trying to get out of the kennel. That would be the EE mix. Clipped her feathers and my blue EE. She was up on the gate to our carport. Silly birds.
So, you got twelve eggs, and only three developing..what state did you get them from? I had the best luck on the lower East Coast states. Upper was awful. Oh I hope you get a couple out of them.
Lisa..yes, Iowa..great state to get eggs from!
Tiny eggs means a little less heat. They can cook up pretty easy with the temp around 100. Even the 99.5. Believe it or not, having them at just 99 is good for the small ones. And, of course, the lower humidity, it tends to makes the eggs warmer if too high. Low 30's, just a little humidity is great. Good luck! Waiting for day 7 for good news on fertility!
