That's wonderful to hear that you were able to save Hathaway! I'll definitely reach out if we have issues. I think I'm most scared that the twin egg will be gross because it's twins. I'm not sure how I'll handle it if it's conjoined. My sister is hoping it's conjoined twins and wants me to give it to her. Anyway, I guess maybe I'll surprise myself. We have a bantam hen who got brutally attacked by roosters a couple months ago. She had a fairly large "chunk" of skin missing. It looked like...well, skinless chicken meat on her back behind her wing. I didn't think she'd survive. It was so, so nasty. If I still ate meat, seeing that would have been enough to put an end to meat for me. Thankfully I have extensive first aid kits for my human and animal family members. I cleaned her wound and put EMT ointment on it. Slowly, day by day she regrew her skin. She now has all her feathers back but she's so stinking spoiled I doubt we could convince her to move back out with the fowl. She has a playpen outside but sprints to the bathroom when she needs to lay an egg because she'll only lay her egg in the bathroom sink.
As for Bill Bill, this guy is WILD and CRAZY! We've had quite a few ducks over the years. We currently have 10 adults. We had mallard's hatch eggs a few years ago then I brought the ducklings inside to brood so they wouldn't get eaten by snakes or something. This was the first time I had eggs in the house though and Bill Bill is the first duckling I was able to talk to in an egg for such a long time. I have a hard time believing he actually recognizes my voice because that's just too amazing, but he goes absolutely nutso when I talk to him. He cries in his brooder box and jumps so high I can hear him hitting the hardware cloth lid (his box is about 11" tall). When I hold him, he runs up to my face and bites all over my face and neck. I've never had a duckling bite this much. When I say his name he seems to get more excited and tries to bite my mouth. I brought him into the bathroom to see the big ducklings. He sat in my hands peeping but the 8 didn't seem to care about him at all. They were probably still pouting because I shooed them out of the shower again this morning.
