We have little Japanese Bantam that went broody about 10 days ago. I tried breaking her from it for a few days, then decided that I would look for some eggs for her to set on and see what happens. Craigslist brought me a couple of egg offers, and I picked up 7 bantam eggs today for her to try. She is much too small to get all 7 under her, so I chose 4 of them and slipped them under her tonight at about 10pm. She seems to be able to cover them all, but I am still a little concerned because she has them resting right on the bare bottom of the nesting box. Is that acceptable, or should I try and add straw? I tried adding some a few days ago while she was sitting on a pair of golf balls, but she pushed it right out so they were on the bare linoleum again. Also, how long can I hold on to the other eggs that I picked up in case the four I chose turn out to be duds? They were all laid this week, so they are no more than 6 days old. I plan to candle the four she is sitting on after 3-4 days, will the others be worth trying after that long? Thanks!
