One of my button pens got some moldy straw in it that must have been carrying a toxin. 2 of the hens died and the 3rd was breathing a little heavy. She recovered fine but has not laid an egg since. It's been about a month now. She is housed inside with a slate male and we have seen them mating in the past and before this incident I hatched some of her eggs. They are under lights in a 48x18" aquarium. Fed 22% game bird starter and ground up evo red meat bites (the red meat version has no poultry meat in it) with 42% protein to up the protein a little. Along with some handy sand (granite based) for grit and dust bathing. Any ideas why no eggs still and will she lay again?
