I have two 18 month old RIR who laid beautifully until April this year when they started laying soft shell eggs. Strangely, they were molting at that time ( we have had crazy weather in BC, Canada this year) so I increased protein to 18% grower and then to 20% starter, they get free access to oyster shell & BOSS, kitchen scraps and free range most days. One girl went back to normal, one has not. Despite everything I’ve been doing this lady still lays an almost complete shelled egg but every single time the top is rubbery and it pops in nestbox even though the shell has calcium deposits on it as tho she is getting too much/not absorbing properly. This hen off and on has a distended abdomen and often you can see she just doesn’t feel well but always rallies, eats, drinks, roosts etc and no one picks on her. It’s been 4 months since a proper egg. Any chance she will sort things out on her own? I am leaning toward this being a calcium absorption issue or something internal like tumours maybe? Anybody have any ideas?
