I finally agreed to let my hen hatch eggs, but the eggs are all in the fridge or are from after I gave them wazine. So, she has 5 fridge eggs (2-3 weeks old) and 6 wazine eggs. We'll see how many we can actually get. To make it more interesting...this is hers and my first time hatching. (She just won't agree to waiting the 3-5 more weeks for good eggs and I won't agree to pay for hatching eggs ). ORIGINAL POST: I have a broody that we have decided we'll let hatch some eggs. The problem is that they were given Wazine about 1.5 weeks ago for a 24 hr period. I have read that those eggs, while fertile, won't hatch. Don't quite understand why, but my guess is that the chemicals transferred to the egg prohibit proper development. My other option is to grab eggs that have been refrigerated from prior to the Wazine. Which is a better choice? Or should I use both and cross my fingers? While I would love to order hatching eggs to solve my problem, we aren't really looking at adding more to the flock right now as much as we are just trying to please our obsessed broody (she's been difficult to break, so we're giving in ). We figure we can give he a few eggs and hope a couple make it. Oh...we live in the desert of So California, so while it will be chilly at night, our coop is warm enough that I think the chicks would be ok with their mama. We won't really be cold during the day for another 6-8 weeks and the rain usually doesn't come until January, so I think we are ok.
