We adopted 6 hens and brought them home last Saturday (5 days ago), all different breeds, all supposedly around 10 months old and healthy layers. So far we've had 3 green eggs (all on different days and in the same nest), 1 broken egg in the run -- I saw it too late to retrieve it, saw a shell remnant so know it was brown, but 3 hens were devouring it as I approached -- and this morning, 1 "rubber egg" -- brown -- on the floor of the coop that I suspect was laid by the Silver-Laced Wyandotte since she was the last one out and making a racket inside. We're feeding them Blue Seal organic layer pellets, oyster shell and grit available, they've been feasting on worms and bugs in the run, plus veggie/fruit scraps, and they free-ranged yesterday for a couple hours. I know they ate well in their previous digs and the previous owners didn't disclose any shell-less egg issues. This is a big transition for them -- they were in a flock of 20 with 3 roosters before. I'm assuming/hoping this is all normal transition stuff (and thinking our 1 Ameraucana is the most well-adjusted of the bunch!) but would love any thoughts/suggestions/feedback since we're brand-new at this!
