I'm pretty sure my hen might be egg bound (fluffy and seems larger, not flying much, clumsy at times - but is eating a bit though not as much as normal and drinking a bit. She's also showed interest in their leafy greens which is good). She has been laying, but hasn't for a week or so. (I have a Zeb hen and Mannikin male left

Sooo, I'm off to get some parrafin oil. Which is the best way to administer? in the seed or directly into her beak? (I don't want to stress her by catching her but I don't think she looks to hard to catch).
I have nest baskets in there, which they like, but I've found she will still lay in the seed dish if I take out the nests. Should I wait till she passes this egg and take out the nests anyway? They like to sleep in there together, so I'd leave them if it doesn't make a difference.
So I also give them egg and biscuit mix whenever I remember. Should I be giving calcium as well? Or just get the parrafin sorted then get the calcium? I"m not breeding, I take the eggs as soon as I see them.
What do you all think? I need to help her asap, and value your opinions

cheers
