i don’t have access to a farm store of any kind (the closest is probably like 4/5 hours away) and i find that oyster shell is just soooo expensive on amazon? i know that it’s necessary, but yeah. i’ve been saving up leftover eggshell from my girls eggs and i’ve been wanting to give it to them (baked and crushed up) but i’m just so worried that they will eat too much of it? especially my top hen, she’s basically a pig in a chicken costume. i’ve given them bits of eggshell just on the ground sometimes but they go sooo crazy for it, is too much calcium possible like this? or does anyone have a link to some affordable oyster shell on amazon or another site? i’m in canada so it needs to be accessible to me. and please don’t yell at me for not giving extra calcium to my girls right away, i’m trying my best. would it be okay for me to just give them a bowl of crushed eggshell until i have the means to order some oyster? they don’t have any issues with laying eggs even if they don’t have the extra calcium- sometimes they lay funny eggs but i’ve only gotten 3 of them out of 3/4 dozen that i’ve gotten from my three girls, and even then i know that funny ones are normal every now and again.
