I have been having a lot of trouble with my linnies and laying eggs, they won't stop unfortunately... This was always a worry of mine of having a female now I am living it.
As far as I can see: You have two female linnies now?
How many eggs have they layed this season?
My Yuki also makes three clutches a year.
Our Avian gave me the following advice:
Please give them enough calcium in combination with vitamin D3, for example Calcivet.
During the egg laying period please feed them hard boiled egg yolk.
Never remove the eggs without replacing them by dummies, otherwise they won't stop laying, because they want to complete their clutch.
When they begin to lay please offer them a nestbox to "breed" their eggs, while breeding they won't lay new ones.
when they leave their clutch after about three weeks. because nothing hatches, please remove all tunnels, caves and everything that could remind them of a parrot's nest from their cages. Only a sleeping cabin where the floor is replaced by branches for sitting is allowed, for example like this:
I hope your girls will stop their permanent egg laying soon.
