I took on 10 banty chickens from a gentleman who said that hawks were carrying off the little ones in his flock. We already have 2 silkies, 1 BO, 1 EE & 1 G Seabright. Of the new bunch, there are 6 silkies that are supposed to be approx 4 months old, 3 cochins that are younger, and a mille fleur d'uccle - age unknown. The silkies are roughly half the size of my hen, Lizzie. We went to the barn on day 4 of the new chickens' stay, and discovered 3 tiny eggs. They look exactly like Lizzie's eggs. The same pearly creamy (almost pink) color and size. I took a pic of the 3 we found, and then placed some of the older chickens eggs beside them to compare. The d'uccle is probably old enough to lay, but these eggs all 3 appeared overnight - literally within a few hours. I was checking my quarantened bunch - even periodically overnight - to make sure everything was good. I doubt that one tiny girl could lay 3 in a few hours. The silkies are tiny & the cochins are even tinier. Any ideas? I wish Lizzie would decide to go broody & I would try to hatch these mystery eggs - even with cold weather coming on!! They would be fine in the barn. Any input?
