Hi all. I have been lurking around these pages for a while but never joined up. So much good information to be had! We have 3 Isa Brown chooks in Adelaide Australia (hot and dry kind of place). We had a worm problem last year, 1 of the chooks (Coco) lost a lot of weight and was obviously not well. Her crest shrunk and she stopped laying. We wormed the chooks, over a couple of efforts the worm problem was solved. Coco has put back on all of the weight she lost but has not started laying again. The other 2 chooks have not stopped laying (1 a day each). This all happened about 6 months ago. Coco is now noticeably larger than the other 2, her legs are yellow and she is probably over weight. Does anyone have advice about how to kick start her laying again? They all share a large 'coop' area and free range in our yard most days. We have not changed their feed other than introducing different things which people have suggested (like corn at the suggestion of the local fodder supplier) to try and get her laying. They have continuous access to layer pellets and are given about a cup or 2 of grain scratch most days, plus scraps... Any advice would be welcomed.
