My chickens yard has Sea Purslane in it. The botanical name is Sesuvium portulacastrum and it is in the carpetweed family. It is considered an herb and eaten in some places. It is said to be salty, probably because it is a coastal, salt tolerant plant. Does anyone know if it can hurt chickens? I googled this but can't find anything. I am new to chickens and got 5 young ones, of which 4 have gotten sick and 3 have died. I am trying to find reasons why and want to rule out this plant as a bad thing. Anybody heard anything on this?
